Rounding the Bases | LineStar’s 2021 MLB DFS Primer & Strategy Guide ⚾
By: Ryan Humphries | @N1TRO on LineStar | @Ryan_Humphries on Twitter
With the start of the 2021 MLB season just days away, it’s finally time to limber up, grab a bat, and step into that on-deck circle! With the pandemic slowly finding itself in the rearview, the start of this baseball season will certainly feel like a piece of normalcy returning to our lives. The light at the end of the tunnel becomes bigger and brighter each day. Of course we're not out of the woods just yet with all this mess, but with fans returning to the ballparks (at least in a limited capacity) and a full 162-game MLB schedule ahead, things will feel much more familiar for baseball fans for the first time in quite a while.
Here at LineStar, we are always looking to give subscribers an edge in any capacity possible. As you can tell by the title, the purpose of this article will be to get you primed for the season while sharing some MLB DFS strategies, tips, and other advice to help you turn your hard earned cash into, hopefully, a lot MORE cash. Whether you are a casual player looking to only throw out a couple bucks on a slate here and there or a grizzled high roller veteran who enters 150 lineups into large tournaments every day, it never hurts to shake the mental cobwebs loose and get a bit of a refresher course for novice and highly experienced DFS players alike. Feel free to bookmark this newsletter to refer back to later on -- otherwise, you can find it linked in the header of the daily newsletters for a good portion of this season. Be advised, this is going to be a long read but if you feel like you may need the help, or if you’re just interested in finding out someone else’s approach to MLB DFS, then I urge you to read it through!
Welcome back, everyone… let’s step up to that batter's box and play some ball, baby!
LineStar Daily Ledger Newsletters
For the 2021 MLB season, I’m ecstatic to have the honor of writing the LineStar Daily Ledger newsletters for the third consecutive year. LineStar subscribers can expect an MLB newsletter for every main slate, Monday thru Friday, which will be delivered to your email inboxes and also linked atop the projections page each weekday. Generally, these will be sent out and posted around 2 to 3 pm ET -- roughly four to five hours before lock. My main goal will be to provide you with a reliable daily introduction into every main slate by giving you an easily digestible slate preview along with highlighting some of the plays and team stacks which I find most appealing or intriguing. To get an idea of what you can expect, feel free to skim through this random edition of the Daily Ledger from last season.
If you have potential suggestions on what you’d like to see added or changed about the newsletters, or if you have any other general questions or concerns, feel free to tag me in the LineStar chat @N1TRO or hit me up anytime on Twitter @Ryan_Humphries!
General MLB Strategy
For anyone new to MLB DFS, you must realize that it is arguably the most volatile sport to play in daily leagues. It is on par with the likes of NHL and soccer. The best players in the game can have a dream match-up and end up batting 0-for-4 while some minor league player who just got called up the night before a game can go 3-for-4 with a home run and a swarm of RBIs against a team’s ace pitcher. Most of baseball’s all-time greats failed 70% of the time when they stepped up to the plate. That’s just how the game works and it’s important not to get discouraged, especially if you hit a bit of a DFS ‘hitter’s slump’ yourself that lasts several days in a row. The MLB regular season is a GRIND and no MLB DFS player is going to be profitable every day.
With that in mind, maintaining strict bankroll management is absolutely crucial. I recommend trying to allocate between 5% and 15% (max) of your overall bankroll towards each main slate you’re planning to play. I would also advise leaning towards the lower end of that percentage range for AT LEAST the first couple weeks of the season. Players can regress both positively and negatively year-to-year for a number of reasons; they joined a new team and are hitting in a better/worse hitter’s ballpark, they suffered/recovered from injuries, they altered something with their mechanics, etc. Relying on data and info from previous seasons is really all we have to go off of early on -- though we can make some educated assessments from spring training as well. It will take, at minimum, two to four weeks worth of games before we really start getting a general grasp on how a hitter is going to perform in 2021. And that time frame is even longer than that for starting pitchers since they will typically only play every five games. I feel much more comfortable in the current season's data once hitters get about 20 games and 60-80 at-bats in. For pitchers, I'd say four to five starts and 25-30 innings pitched is a reasonable enough sample size that we can trust as well.
Remember that baseball is a sport in which you will need to stay vigilant as the slate lock time approaches. Similar to the NBA, starting lineups can often be shuffled around and the possibility of an unexpected last minute scratch is always present. Value can also open up in this situation if a cheap hitter is unexpectedly slotted in at lead-off or near the top of the order. Teams are typically pretty good about announcing lineups well ahead of their scheduled game times, so an unexpected scratch after a specific game locks is a fairly rare occurrence, but just be aware that it does happen. The fact that coronavirus is still a factor will heighten these late scratch risks but hopefully, those issues are few and far between this season. Both DraftKings and FanDuel feature late swap, so you’ll be covered if one of your late game players ends up sitting out (IF it is announced in time) but again, this requires you to stay on top of things throughout the day and into the evening!
Also, as a general rule of thumb, be aware of the MLB DFS scoring system for your preferred site!
Cash Game Strategy
I’ll preface this by saying that there is no certified, cookie cutter method to playing DFS -- especially when it comes to baseball. Not everyone is going to agree with all aspects of my approach, and that is 100% fine! I’m simply going to highlight the methods and processes that a decade of DFS experience has led me to utilize.
For any given MLB slate, I lean towards allocating more money into cash games (double-ups, triple-ups, head-to-heads, 50/50s) as opposed to GPPs (guaranteed prize pools aka tournaments). In general, my daily bankroll spend will have around 60-70% invested into cash games, 30-40% in GPPs. Though, occasionally, I will go all out in tournament mode and throw 100% of my daily spend into GPPs. While snagging that massive five or six figure payday is always a goal, the odds of it actually happening are slim. I’m more interested in long term ROI by building around the players in the most optimal spots as opposed to pulling the lever on the “contrarian slot machine” and hoping one of my lineups hits in the top 0.005%. That isn’t to say I don’t look for those high-upside GPP leverage plays but in such a statistically driven sport, I tend to prefer putting the majority of my money toward what makes the most sense, and the Daily Ledger newsletters will often reflect that. But, to reiterate, I will still target plenty of GPP-centric plays to highlight throughout the newsletters.
A common strategy for cash game formats in any sport is to focus on just one cash game lineup to enter into contests. I am no different in that regard when it comes to baseball. In a 100-player 50/50 contest, since 1st place gets paid out the same amount as 50th place, I never worry about potential ownership in my cash lineup. It’s perfectly fine to have your cash lineup filled with more obvious and chalky (highly owned) players. Also if a player is, say, 50% owned in a double-up and puts up a dud performance, you are essentially protected from falling too far down in the standings -- so sometimes high ownership turns out to be a good thing. Playing a guy who was a considerably riskier option will obviously burn you much more in cash contests if he duds and is <5% owned. I will get more into ‘stacking’ in a moment, but when it comes to constructing your cash lineup for slates that feature a fair amount of games (at least six or seven) you should typically use mostly one-off hitters or mini-stacks (two or three batters on the same team) who are in excellent match-ups, preferably with a spot higher up in the batting order (1 thru 5). I will personally almost never have more than three hitters on the same team in my cash lineup build.
A quick tip related to cash lineup construction: ALWAYS throw it into some sort of GPP just in case it ends up being full of the nut plays! Even if it’s just a $0.25 entry or something. It happens all the time where I’ll see someone say something like “I would’ve won $25,000 if I played my cash lineup with my tournament entries.” If you target the ‘safest’ guys for your cash lineup, it would make sense that, eventually, it absolutely goes off, right? And, many times, the players who you believe are going to be chalk end up being <10% owned in GPPs. There's no excuse to not throw that cash lineup into some kind of tourney with a nice payout. Trust me, just do it!
GPP Strategy: Team Stacking & Contest Selection
Team stacking is the single most powerful approach you can deploy when building your GPP lineups. For those that may be unaware of what “stacking” in MLB DFS entails, it is simply drafting two to five hitters who are on the same team and bat directly by, or near, one another in the lineup. Most people gravitate towards stacking guys near the top of the order (1 thru 5) but you can really set yourself apart by including players who are further back in the order by going with something like batters 3-7 in a five man stack. An intriguing and often overlooked method is to create “wraparound stacks” such as playing the 8, 9, 1, 2, 3 batters, for example. But I’d usually lean towards reserving that strategy for smaller slates where it is much more difficult to be different.
Utilizing the stacking approach in tournaments is often done by using multiple teams. For instance, on DraftKings, a 4-4 stack would be four batters stacked together from two separate teams -- but you can also build 5-3 stacks, 4-3 stacks with a one-off hitter, 3-3-2 stacks, 2-2-2-2 stacks, and so on. It’s also alright if you want to skip over a specific batter in the order, especially if you’re only trying to stack righty or lefty batters to take advantage of positive splits against LHPs or RHPs -- aka “platoon splits”.
When determining what teams you want to stack, particularly if you’re including players towards the bottom of the order, it can occasionally be to your advantage to target road teams. This is because road teams are guaranteed to bat in the 9th inning no matter what. Most are aware of how this works, but for those who don't know, home teams bat in the bottom of each inning of the game. If the home team is winning after the top of the 9th inning, there is no point for them to hit in the bottom of the 9th and the game is over. Players who were due up will miss out on that extra at-bat. One extra at-bat can make all the difference, especially if you have multiple guys consecutively stacked who would have benefited from hitting in the final inning. But do note, this doesn't really sway me off of stacking home teams... it's just a small plus to rostering road team stacks.
Finding low-owned stacks will also give you a pretty clear advantage in GPPs in terms of being contrarian. Hardly anyone is going to take a chance on stacking a team facing a pitcher like Gerrit Cole or Jacob deGrom. But while those guys are world class pitchers, they're also facing literally the best hitters in the world as well. Aces get rocked quite regularly so, if you're willing to take on the added risk, then don't hesitate to throw one of those against the grain stacks. Hit up our boy @ZeroInDenver in the chat if you want to hear more on this subject.
Now, is stacking a MUST for GPPs? Absolutely not. Plenty of MLB DFS tournaments are won with lineups that are littered with a bunch of one-off hitters and maybe one or two mini two-man stacks. But if a baseball team goes off for 10+ runs on any given day, you can almost guarantee that multiple hitters from that team will be found in GPP winning lineups.
This bit applies to all MLB DFS formats, but the weather is also a significant factor in baseball and can help in predicting potential high or low scoring games. More scoring can be expected in stadium conditions that feature high altitude (which, as many know, is why games at Coors Field are always a popular DFS target) where the air is thinner a balls carry further. Heavy humidity and hotter air temperatures (think somewhere like Truist Park in Atlanta during the summer) can also help baseballs travel further. Mix any of those conditions with winds blowing towards the outfield and you have a recipe for an ideal game to target hitters in. You can also apply this logic to upgrade or downgrade pitchers. Cool temperatures in the 40s or 50s with winds blowing in at 15+ mph? That would be a great pitching environment. It’s also not unusual for games to get delayed or even postponed due to heavy lingering rain or nearby lightning. There are several quality sources for up-to-date MLB weather info, especially on Twitter, but LineStar also has you covered every day when you check out the MLB Daily Dashboard at the bottom of every game’s lineup card which features up-to-date hour-by-hour forecasts as well as postponement risk percentages.
One final thing I want to talk about here, which also applies to all contest formats, but mostly GPPs, is contest selection. Don’t feel obligated to get sucked into those huge tournaments with six figure payouts and 150-max entries allowed. If you’re someone who likes to stick to one lineup, or perhaps a bit more, then take advantage of contests like single entry tournaments or 3-entry max. You’re at a pretty significant disadvantage if you have far less than 150 lineups entered into a contest that allows 150-max entries. Many people also don’t expand their horizons when it comes to contest selection and they end up missing out on certain formats like quintuple-ups, 10x multipliers, winner-take-alls, satellites, etc. If your preference is to throw one lineup into the largest GPP of the day that has a $100k+ payout to first place and leave it at that, then I won’t stop ya. Just know that it’s probably not the safest approach for long term ROI.
So, taking much of what I’ve talked about so far, here is a general example of what my personal contest selection would look like if I wanted to play, say, $50 on DraftKings:
Cash Game Bankroll Allocation ($30 total):
$25 SE (single entry) Double-Up
$5 Triple-Up
GPP Bankroll Allocation ($20 total):
$5 to max enter a $0.25 GPP (20 lineups)
$9 in a three-entry max $3 GPP (three lineups)
$3 in a three-entry max $1 winner-take-all - $100 to 1st (three lineups)
$3 in three $1 quintuple-ups (usually using my cash game lineup)
Again, this is just a general example of what I would do and my contest selection definitely changes quite a bit, especially if a slate feels geared more towards GPPs. If you have different ideas on what contests you believe you should enter, I am not going to argue! At the end of the day, play how you want while being aware that DFS is simply inherently risky.
Key Statistics & Other Info to Focus On
These days, the sport of baseball, while simple at its core, has dozens upon dozens of statistical categories that are recorded. Ultimately, there is a vast amount of randomness to this game that will never be possible to foresee. And, after all, the unpredictability is part of the beauty of baseball. However, stats and other information can absolutely assist in providing us with at least a sliver of a predictive edge which can help is in DFS. In this section, I’ll hit on what information I believe to be of the most helpful whether you're building one lineup or 100+. You’ll see pretty much every one of these statistics mentioned in the daily newsletters throughout the season.
LineStar does an excellent job at showing you pretty much all of the most important baseball stats that you could ask for but if they included every one of them, things would get pretty cluttered and possibly overwhelming. If you really want to get down and dirty with other numbers, data, and splits, a free resource I recommend using is FanGraphs.com. If you've never used FanGraphs, it does take a bit of time to get used to (and it's much easier to navigate on a laptop or desktop), but feel free to DM me on Twitter if you need any help. Pairing the vast amount of data provided there along with LineStar essentially gives you pretty much everything you could ever need for daily MLB research, in my opinion (along with a few Twitter sources).
Pitching ⚾
Pitching is arguably the most important part of MLB DFS due to pitchers possessing less variance than hitters and quality arms will routinely be my top priority unless is just an ultra offensive-focused slate. Your lineup can still land inside the cash line with a poor performance from two or three batters but if your pitcher(s) get shelled, the chances of still cashing drop drastically. So, what info and statistics do I want to delve into when searching for the most ideal pitchers to roster?
Primary Pitching Stats & Info
This is the go-to information that helps me find preferred pitching plays and will be the most common things you’ll see referenced in the daily newsletters.
Vegas Totals & Moneyline Favorites
Pretty straightforward here. If a pitcher is a -250 favorite with <3.5 implied runs projected to be scored against his team, then they should clearly be in a good spot for that night. Typically, only high-level aces will get those kinds of odds and implied runs against. Still, a solid starter will garner around -170 moneyline odds and <4.5 implied runs against.
kRate (aka Strikeout Percentage or K%)
Strikeouts carry huge weight when it comes to DFS scoring for pitchers and you definitely want guys with high K upside (six strikeouts at minimum for your more expensive pitchers). I can live with pitchers who will likely give up some hits and a few runs if it means that they can provide double-digit strikeout upside.
I also prefer the kRate stat over K/9 since kRate can indicate a more dominant and efficient pitcher.
For Example:
Pitcher A: 7 IP, 7 H, 3 BB, 6K
Pitcher B: 7 IP, 3 H, 1 BB, 6K
Both pitchers have the same K/9 but Pitcher A faced 31 batters (19.4% kRate) while Pitcher B only faced 25 batters (24% kRate). It’s also important to take note of an opposing team’s kRate splits against RHPs/LHPs. A low strikeout pitcher can see a reasonable boost in K upside if the opposing team is striking out a lot.
xFIP (Expected Field Independent Pitching)
xFIP is a further advanced stat on top of FIP that attempts to predict a more accurate future ERA for a pitcher. The standard ERA stat can be quite misleading and may not always tell the true story of a pitcher's skill. xFIP can help by trying to remove the “luck” and randomness factors that can dramatically alter a pitcher’s ERA. When a pitcher’s xFIP is much different from his ERA (especially early in the season) it can be a good way to find out if someone may be undervalued or overvalued.
Example: If a pitcher’s ERA is 3.20 but he has an xFIP of 4.80, he could be getting “lucky” and is probably due to regress. For DFS purposes, he could be considered overvalued and riskier than someone with a 4.15 ERA but a 3.40 xFIP.
League average xFIP will usually be around 3.80. Anything below 3.20 could be considered excellent while anything around or above 4.30 would be considered poor.
WHIP (Walks plus Hits per Inning Pitched)
A pitcher’s fundamental role is to limit runs which is most obviously done by preventing base runners. As such, knowing the average number of walks and hits per inning a guy gives up is quite useful. Since the WHIP stat weighs a walk the same as a home run, it definitely isn’t a ‘catch-all’ kind of metric but it is a solid starting point when researching various pitchers on any given slate.
An average pitcher’s WHIP will be somewhere around 1.30. A 1.00 WHIP (or lower) could be considered elite while a 1.60+ WHIP is awful.
Secondary Pitching Stats & Info
I will occasionally use the stats/info below to further dig into pitchers for a specific slate and they will sometimes be referenced in the daily newsletters.
SIERA (Skill-Interactive ERA)
As much as xFIP attempts to be a “catch all” statistic by predicting a pitcher’s true skill while focusing on strikeouts, walks, and home runs, SIERA further expands on pitcher skill prediction by factoring in balls in play. It attempts to explain why certain pitchers are more (or less) successful at limiting hits and preventing runs and has been proven to be very predictive of essentially every meaningful pitching statistic.
League average SIERA will usually be around 3.90. Anything below 3.25 could be considered excellent while anything around or above 4.50 would be considered poor.
SwStr% (Swinging Strike Percentage)
SwStr% is calculated by taking swings and misses and dividing that by total pitches. It’s quickly becoming one of my favorite secondary pitching stats and may move up to a primary stat for me this season. SwStr% is important because it can help indicate how unhittable a pitcher is and show whether or not their kRate is over or underperforming. Generally, you can double a pitcher’s SwStr% and that’s about where their kRate *should* be.
League average SwStr% will be around 10%. Anything above 14% is elite and anything below 8.5% would be poor.
GB% (Ground Ball %), FB% (Fly Ball %), LD % (Line Drive %)
These metrics can help indicate what type of pitcher someone is. Not every pitcher has to fall under the category of "ground ball pitcher" or "fly ball pitcher" but many do. Additionally, since line drives go for hits far more often than GBs & FBs, rostering pitchers with a high LD% can be a dangerous investment. Ground balls go for hits more often than fly balls, but when fly balls do fall for hits, they go for often extra bases more often than ground balls.
Average GB% among pitchers is around 44%. A pitcher is considered a "ground ball pitcher" when they reach above 50% GB%.
Average FB% among pitchers is around 35%. A pitcher is considered a "fly ball pitcher" when they reach near or above a 40% FB%.
Average LD% among pitchers is about 20%. A pitcher with a LD% significantly higher than that is likely having a bad time.
Note: I'll get into Hard% below in the batting section, but a fly ball pitcher with a Hard% near or above 40% is someone you may want to target against using opposing power hitters. Those pitchers are more likely to give up home runs.
Batting 💥
As I alluded to above, no matter how high of a price you pay for any given hitter or what kind of hot streak they're on, there is always a reasonable chance they will go 0-for-4 and give you a fat goose egg on the night. That’s just baseball for ya and an aspect of MLB DFS that you’ll have to live with. But that is also why selecting the more ideal pitchers, usually by paying up, can be the most predictable path to fantasy points and thus more important in the long run, as opposed to taking a chance on several high-dollar hitters. Of course, that isn’t to say you always need to play expensive ace pitchers and settle for a bunch of cheap bats. Many times paying up for several big bats in killer match-ups is perfectly fine as long as you aren’t sacrificing too much in the pitching department. But here is some other info and stats that I look into for not only finding candidates for team stacks but for one-off hitters to build around as well:
Note: It may be obvious, but you can use many of the stats and info that I mentioned with pitching above to find bad or struggling pitchers to play hitters against. The same is true for the hitting stats and info below when targeting pitchers versus teams who are struggling in specific metrics.
Example: If a team is posting a 28% kRate and a sub-.300 wOBA against right-handed pitchers over the last month, it’s probably a good idea to consider any (talented) opposing RHP they may be going up against.
Primary Batting Stats & Info
This is the go-to information that helps me find preferred hitters and will be the most common things you’ll see referenced in the daily newsletters.
Vegas Implied Run Total
Again, this is pretty straightforward. Any team projected to score 5.0+ runs by the bookies would seem to make for a strong team to target or stack up for the offense. When teams are really hot or in a great spot, they could carry a 6.0+ implied run total. It also won't be uncommon for the Colorado Rockies and visiting teams to carry implied run totals near or above 7.0 runs when Coors Field is in play... especially in warmer conditions.
Ballpark/Weather Factor
This was hit on above, but if a team is in a hitter’s ballpark or will get a boost from hot/humid weather with winds blowing out, they’re an offense to target (sometimes even if they're going up against an ace-level pitcher).
wOBA (Weighted On-Base Average)
wOBA is one of the best “catch all” offensive statistics available. Where batting average weighs all hits the same, wOBA weighs each aspect of hitting (singles, doubles, triples, home runs) proportionally to their actual run value and better illustrates a player’s overall offensive contribution. This is my go-to statistic I pay attention to when looking for cash-safe hitters.
An average wOBA is around .320. Elite hitters will sport a wOBA of .400+ while the worst hitters will have a wOBA of .290 or lower.
ISO (Isolated Power)
ISO is a pretty straightforward stat as well. It gives you an idea of a hitter’s raw power and how often they hit for extra bases. It can be very useful particularly when building GPP lineups where you want players with major home run upside.
Example:
Player A: 10 ABs, 4 H, 4 Singles, 0 HR
Player B: 10 ABs, 1 H, 0 Singles, 1 HR
Player A has a .400 batting average and .400 slugging percentage but an ISO of .000. Player B has a .100 batting average and .400 slugging percentage but an ISO of .300. If you’re looking for major DFS scoring upside, Player B may be who you’d like to target for GPPs while Player A profiles as more of a safer cash gameplay.
Some of the most elite power hitters will have an ISO of .250 or above. An average ISO will be around .140 and a poor ISO would be 0.100 or lower.
Splits vs. RHPs/LHPs
It is pretty well known that for the vast majority of players, right-handed batters tend to struggle more against right-handed pitchers and, of course, the same is true for LHBs vs. LHPs. There are several factors for why these splits exist, which I won’t really get too deep into, but the primary reason is that hitters tend to read pitches better when they are breaking towards them on the inside of the plate, rather than away. There are some exceptions in which the opposite is true. Those players are referred to as “reverse splits hitters/pitchers.” Whether they exhibit reverse-splits or traditional split tendencies, it can be very useful to look into a player’s righty/lefty splits to see if they have a potential advantageous match-up versus the opposing starting pitcher. It’s also worth mentioning that switch hitters almost always hit noticeably better from one side of the plate over the other.
When team stacking, I will often stack one side of the plate if the split advantage appears high enough to make it seem worth it. The main caveat here is the fact that a pitcher could get pulled early and a batter could end up with unfavorable bullpen match-ups for much of the game. However, if that hitter (or hitters) is a determining factor as to why the starting pitcher got pulled (e.g. your team stack shelled the opposing SP for seven hits, two homers, and five runs in the first two innings), then you probably won’t feel compelled to complain too much.
wRC+ (Weighted Runs Created Plus)
wRC+ is a terrific stat which I love referring to -- especially because, as much as I love all these numbers and analytics, quick mental math is not my expertise. Simply put, wRC+ shows just how impactful a player is for his respective team and very accurately indicates their overall offensive value when compared to the league average. Similar to wOBA, wRC+ attempts to better credit a hitter for more valuable hits (doubles, triples, and home runs) but what sets this metric apart is that it takes into account park factors and the current scoring climate in the league at any given time. This stat is scaled each year so that a wRC+ of 100 is precisely the league average. Every point above or below that is one percentage point better or worse than the league average. So it’s a metric that helps you visualize a player's effectiveness via some super simple mental math. If a batter is posting a 140 wRC+ then he is essentially providing 40% more offensive run value than the average hitter in the MLB.
The most elite hitters will hold a wRC+ of 160 or better and the worst hitters will have a wRC+ of 60 or below. And, again, a 100 wRC+ is exactly league average no matter what.
Secondary Batting Stats & Info
I will occasionally use the stats/info below to further dig into batters for a specific slate and they will sometimes be referenced in the daily newsletters.
Hard% (Hard-hit Rate)
Hard-hit Rate is a borderline primary stat for me and one that I will reference quite a bit in my own daily research as well as in the newsletters. In a way, it helps illustrate a hitter’s power somewhat similarly to ISO, but by different means. Essentially a ball is considered a “hard hit” ball if the exit velocity is 95+ mph. That 95 mph threshold is statistically proven to be the general starting point for where exit velocity really starts to improve a hitter’s batting averages and extra base/home run upside. Per MLB.com, in 2018, balls that were “hard hit” resulted in a .524 AVG, 1.047 SLG, and .653 wOBA. Clearly, those are monstrous numbers.
An elite Hard% would be above 40%, an average Hard% would be about 30% and anything below 20% would be considered awful.
BABIP (Batting Average on Balls in Play)
BABIP measures how often a ball in play goes for a hit. A ball is considered “in play” when a plate appearance ends in something other than a home run, sacrificed bunt, strikeout, walk, hit batter, or catcher’s interference. Around 30% of all balls in play fall for hits. Three factors influence BABIP: defense, luck, and skill level. To keep it short, BABIP helps determine if a player is getting unlucky/lucky or if he is falling victim to or taking advantage of, strong/poor defenses. A player’s seasonal BABIP can also be useful when compared to their career BABIP.
Example: If a player has a career BABIP of .330 over the last three seasons but starts off this season with a .270 BABIP after the first two weeks, then it is very likely that this player is either getting unlucky or they’re facing tough defenses and should be due to progress back towards that .330 average.
The league average BABIP will stick around .300. The elite hitters will sport .350 or better while the worst hitters in the MLB will be around .260.
Opposing Bullpen Strength
This is an often overlooked aspect in MLB DFS. When considering batters and their pitching match-ups, most people really only weigh the quality of the opposing starter. These days, a starting pitcher can typically be estimated to pitch 5 or 6 innings but that still leaves about a third of innings to be handled by relievers. If a particular bullpen is struggling then that is a potential one or two at-bats that a hitter will have against below average or simply outright bad pitching (though, the opposite can of course be true against strong bullpens). If the initial starter gets shellacked early, then the majority of the game could be against the bullpen. If it's a bad bullpen, this can be where low-owned stacks really thrive if they do manage to go off early against the starter.
You also have to consider the fact that many teams without a cemented five-man pitching rotation will elect to run with an “opener + long reliever/bullpen” strategy. As in, their SP will pitch only one or two innings, by design, and will be followed by a long reliever (who would usually be expected to pitch anywhere from two to five innings) or either just a platoon of bullpen arms for the rest of the game. In that scenario, it can be really tough to rely on righty/lefty splits from the opposing offense. But you can also upgrade/downgrade a potential team stack depending on the quality of the opposing bullpen.

Hopefully, I didn't put too many people to sleep with all of the statistical yadda yadda. In summary, there are just so many different metrics and statistical categories in baseball and even more ways to use them in various DFS strategies – it’s easy for everything to seem overwhelming. Don’t let it bog you down too much, especially if you are new to the sport. At the end of the day, baseball relies heavily on luck and volatility, so no single approach is guaranteed to print out money. We just have to utilize whatever tools and information are at our disposal in an attempt to gain a theoretical edge on the field.
Speaking of utilizing tools, LineStar has plenty of them to help you out this season so don’t let ‘em go to waste!
The Daily Matchup feature is a fantastic way to visualize players that appear to be in the best/worst spots and every column is sortable. Also, you can quickly rotate between specific slates, pitchers, batters and their designated positions.
You can also see how players are stacking up on every slate with LineStar’s nifty Live Scoring page!
Of course, the Lineup Builder & Optimizer (located on the “Projections” page on desktop) can be handy when you’re struggling to fill out a specific lineup. It is especially helpful when playing in MME (Massive Multi-Entry) GPP tournaments and you want to quickly create a large number of lineups instantaneously. There are several base models to choose from and plenty of other advanced sorting tools to help you fine tune your preferences. Simply configure your preferences, generate lineups, and export them to your preferred DFS site. It may take some experimentation on your part, but eventually you can come across a system that works more specifically for you!
Check out ownership projections which updates once a slate goes live!
And of course, on the main Projections Page you will have full access to player projections, historical player fantasy performances, positive & negative trends, the ability to sort through things like "most loved" players as voted on by LineStar users, detailed advanced statistical sorters, community chat, recent MLB news, and much, much more!
These are just some of the tools LineStar provides for your arsenal. Be sure to familiarize yourself with everything you have here at your disposal!
