Main Slate Rundown 🏟
A new week, and one of the final weeks, of MLB regular season action will get rolling with a seven-game Monday main slate! It’s generally looking like a fairly standard slate -- pretty decent pitching and some worthwhile hitting/stack options. Weather also won’t be a concern, which is always a bonus. We’ll keep this intro short and jump right into the action. Best of luck!

Pitchers to Consider ⚾
Kyle Bradish (RHP), BAL | DK: $9.2k, FD: $9.8k | at CWS
Bradish had a long road back from Tommy John surgery recovery, but in his three starts since his return, he has put up some promising results. His 3.60 ERA is backed up by a stronger 3.10 xFIP, and Bradish has also pitched to a 0.94 WHIP, 6.2% BB%, and a huge 32.3% kRate. It’s a small sample size, of course, but Bradish seems to have recovered well from his elbow injury/surgery.
Bradish’s matchup with the White Sox is intriguing. Though it’s devoid of any household names, this CWS offense has shown some scrappiness since the MLB returned from the All-Star Break. But, performing above expectations for this team generally means that they’ve been an average offense. That’s reflected in their 102 wRC+ vs. RHPs L2Weeks, which places them 17th in MLB. They’ve also been striking out a fair amount, with a 25.8% kRate (7th highest) in that same span. Bradish will likely be limited to around 80-85 pitches, as there is no real reason for the Orioles, who are firmly outside the playoff picture, to push him further than that. But that could be enough of a workload for Bradish to record a quality start (6.0+ IP, ≤ 3 ER) with plenty of strikeouts along the way.
Jason Alexander (RHP), HOU | DK: $7.7k, FD: $7.1k | vs. TEX
Alexander may not be the most exciting option, but he has been settling into his big league starting role nicely, and the results have followed. Since August 4th (7 GS, 41.0 IP), he’s put up a 2.20 ERA, 3.78 xFIP, .205 opp AVG, 0.98 WHIP, 21.6% kRate, and 5.6% BB%. Pretty pedestrian kRate, but everything else has been solid.
Meanwhile, the Rangers head into this game ranking 23rd or worse in AVG, OPS, wOBA, ISO, and wRC+ against RHPs L2Weeks. Their 21.2% kRate in that stretch hasn’t been overly high, but it's pretty close to league average. So, while the strikeout upside is limited overall, Alexander should still stitch together a quality start this evening.

Trey Yesavage (RHP), TOR | DK: $7.5k, FD: $7.3k | at TB
We’ve got a top prospect making his big league debut tonight in Trey Yesavage. The 22-year-old righty was drafted just last year as the 20th overall pick. He has been blazing through the Blue Jays’ minor league system and now looks like he may be a part of Toronto’s postseason plan. Yesavage is the top overall prospect for Toronto and the #25 overall prospect in baseball (per MLB.com). Across 98.0 IP in Low-A, High-A, Double-A, and Triple-A, Yesavage has thoroughly impressed with a 3.12 ERA, 2.54 xFIP, .156 opp AVG, 0.97 WHIP, and a towering 41.1% kRate. As for his arsenal, Yesavage has a fastball that usually sits in the 93-95 mph range and can touch 97, playing up because of his high release point and strong carry through the zone. He mixes in a slider/cutter, a curveball, and a splitter that stands out as a true weapon with late depth and plenty of swing-and-miss potential. Most scouts view Yesavage as a strong #3 starter with back-end #2 starter upside in a big league rotation. Reportedly, Yesavage will not have any workload limitations for his MLB debut.
It’s not the easiest spot for a young prospect making his first start in the bigs. He’ll be on the road versus an offense with some dangerous hitters sprinkled throughout the lineup. But, if we’re looking at recent sample sizes, the Rays have only been a bit above average against RHPs L2Weeks, based on their 106 wRC+ in that span (ranks 12th), and their 22.5% kRate has been right at league average (15th). There will always be some added risk attached to any pitching prospect making their MLB debut, regardless of matchup, but if Yesavage lives up to his billing and pedigree, then he could put forth a successful outing this evening.
Trey Day is coming to Toronto.

Team Stacks to Target 🎯
Disclaimer: Stacking in MLB DFS is not a requirement but it is a very common strategy used to take down GPPs. This strategy is covered in more detail in the MLB DFS strategy guide linked in the header at the top of this newsletter. Check out the MLB StackFinder on LineStar.
Toronto Blue Jays vs. Joe Boyle (RHP), TB
Joe Boyle’s rough stretch of starts resulted in him being demoted to the minor leagues, but he has since been recalled to make a spot start tonight. He hasn’t pitched in an MLB game in nearly a month, but across his last five big league starts, Boyle has struggled to a 9.68 ERA, 6.00 xFIP, .312 opp AVG, .434 opp wOBA, 2.21 WHIP, 2.50 HR/9 Rate, and 55.9% Left-on-Base%. Ugly stuff. He is decent from a strikeout perspective (22.5% kRate L5Starts), but the Blue Jays are among the most difficult lineups to strike out.
Toronto has also simply been one of the best offenses in MLB of late. Against RHPs L2Weeks, they’re 3rd in AVG (.296), OPS (.865), wOBA (.368), and wRC+ (138) while ranking 5th in ISO (.209). Steinbrenner Field has also ranked as the #10 most hitter-friendly ballpark this season, and the Rays’ bullpen has been a touch below-average in recent weeks, so that is a couple more factors working in the favor of a Blue Jays stack.
Favorite TOR Bats: George Springer, Daulton Varsho, Vlad Guerrero Jr.
Bargain Bats: Ernie Clement, Davis Schneider
New York Yankees vs. Simeon Woods Richardson (RHP), MIN
The Yankees top the slate with a 5.1 implied run total. They don’t head in in stellar form (103 wRC+ vs. RHPs L2Weeks), but we know this team has the tendency to really pop and brings ample HR upside to the table. They do lead all MLB teams, by a wide margin, in HRs (46), ISO (.247), and HR/FB Rate (21.6%) against RHPs over the last month.
That should play well versus Simeon Woods Richardson, who owns a slate-high 51.4% FlyBall%. Across his last five starts, SWR has put up a 6.75 ERA, 5.43 xFIP, 1.59 WHIP, 2.50 HR/9 Rate, 13.4% BB%, and 18.2% HR/FB Rate. His recent struggles with walks could lead to multiple multi-run HRs for this Yanks lineup this evening. The Twins’ bullpen has also been terrible, posting an MLB-worst 7.95 ERA, 1.83 WHIP, and .318 opp AVG over the last two weeks, so there is plenty of upside for this Yankees stack even when Woods Richardson is taken off the mound.
Favorite NYY Bats: Aaron Judge, Jazz Chisholm Jr., Giancarlo Stanton
Bargain Bat: Jose Caballero

Low-Owned Stack That Just Might Work Out 🤔
Philadelphia Phillies vs. Emmet Sheehan (RHP), LAD
Eight of nine hitters in the projected Phillies lineup have a ≤ 11% pOwn%. Emmet Sheehan has been on a roll (0.98 WHIP, 32.5% kRate L5Starts), but the Phillies have also been crushing right-handed pitching. They lead the MLB in AVG (.331), OPS (.972), wOBA (.411), and wRC+ (164) against RHPs L2Weeks while posting a 17.7% HR/FB Rate. The Dodgers’ bullpen has also had some issues of late, posting the 10th worst ERA (4.84) L2Weeks.
Favorite PHI Bats: Kyle Schwarber, Bryce Harper, Harrison Bader
Bargain Bat: Brandon Marsh
