Chicago Cubs vs Philadelphia Phillies @5:40 PM CT

It may be early in the season, but Harper has started 2026 on fire: 

99th Percentile – xSLG 

98th Percentile – xwOBA 

91st Percentile – Barrel % 

86th Percentile – xBA

Against righty starters this season, Harper has 3+ HRR in 6/9 games, including 4 straight games at home.

We already targeted a hot lefty batter against Assad in the last start. Jonathan Aranda ended up getting 2 hits and an RBI that game.

Last year, Assad gave up a .293 batting average vs LHH. Harper this year has a .286 AVG and a .990 OPS vs RHP.

It’s also nice Harper gets Turner and Schwarber batting ahead of him today. If Harper gets 5 at-bats today, 2-3 should have runners on base.

The Pick: Bryce Harper Over 1.5 H+R+RBI 1u (-140)

Miami Marlins vs Atlanta Braves @6:15 PM CT

The reigning NL ROY has been a machine this year. On the year he is over this line in 12/16 games (75%). Vs RHP that number jumps to 80%. Since 4/5 he is over this line in 6/7 games, with the one miss reaching base twice but not scoring a run.

While Eury has the ability to shut down a game, recently he has been susceptible to damage. Across 3 games Eury has a 5.06 ERA and 8th percentile Barrel% (16.7%).

He gets Atlanta today, a team he struggles against. The team is hitting .355 and slugging .806 vs Eury. The best hitter vs Eury is Drake Baldwin, who has 2 home runs in 5 career PAs.

Drake historically is a Marlins killer. He has 2+ HRR in 9/10 games vs Miami, and 3+ in 6/10. He has a .375 BA with a 1.179 OPS vs Miami.

Just betting on a hot hitter to stay hot. 2 HRR should be a lock.

The Pick: Drake Baldwin Over 1.5 H+R+RBI 1u (-113)

Cleveland Guardians vs St. Louis Cardinals @6:45 PM CT

The Big G is red hot to start 2026. He has only allowed 5 hits across just under 18 innings pitched. His xBA is only .152, which ranks in the 95th percentile.

Williams finished under this line in 63% of games last year. In his last 10 games overall he is under in 8/10 (80%).

Outside of Jordan Walker, this Cardinals offense is not good. They rank second to last in Hits vs RHP (72), and 6th worst in BA vs RHP (.212). Of the 11 RHP starters they have faced, 9 have gone under this line. The two that missed were Miles Mikolas and Brayan Bello, not exactly top tier arms.

One thing STL IS good at is walking. They have a 10.8 BB% vs RHP which puts them in the top 10. Gavin can struggle at times with the walks, which is GREAT for an Under HA prop as walks eat pitches. 8/11 RHP starters that have faced STL have 2+ BBs.

Gavin should have another great day on the mound today vs a struggling STL lineup.

The Pick: Gavin Williams Under 4.5 Hits Allowed 1u (-110)
