Pitchers to stream on Saturday

  • Until Pittsburgh Pirates RHP Mitch Keller sees his rostership eclipse 50%, he's going to be a mainstay in this space. He's up to seven quality starts, including his last three outings. Keller fanned 19 with just five walks and no homers allowed in those 19 frames. Next up is a home date with the Milwaukee Brewers, who tote the sixth lowest wOBA facing right-handers into PNC Park.

  • Los Angeles Angels RHP Jose Soriano is one skill away from taking the next step. His four-seam and two-seam fastballs both average around 97-mph. He throws a knuckle-curve at 85-mph, serving as his changeup. Soriano's issue is control as only 60% of his pitches are strikes, well below the 63.7% league average. On Friday, Soriano faces one of the least patient teams in the league with the Angels hosting the Miami Marlins. If Soriano trusts his stuff, he should post his sixth quality start in 11 outings.

  • While an offensive breakout for the Baltimore Orioles seems inevitable, their slump has transpired long enough to not worry about stream against them. Boston Red Sox RHP Hunter Dobbins is the type of pitcher that can keep the Orioles mired in the doldrums. He's not overpowering, but Dobbins pounds the zone, walking just five batters in 32 1/3 innings. He's also keeping the ball in the yard with just three homers allowed all season.

Pitchers to avoid on Saturday

  • With a 6-1 record and 2.53 ERA, RHP Casey Mize is one of the reasons the Detroit Tigers entered the weekend with the best record in baseball. However, he's been sidelined with a sore hamstring, last appearing on May 8. Mize is ticketed to come off the 15-day IL on Saturday to face the Cleveland Guardians in the Motor City. Mize eschewed rehab, instead getting ready via bullpen sessions so he's likely to be on a workload restriction. The Guardians fan at the lowest rate in the league, further dampening Mize's points potential. It's best to look elsewhere for fantasy purposes.

Betting tips

Best/worst pitcher/hitter matchups and betting projections are generated by THE BAT X, a system created by Derek Carty using advanced methods like those used in MLB front offices, accounting for a variety of factors including player talent, ballparks, bullpens, weather, umpires, defense, catcher pitch-framing, and lots more. Betting projections for every player, team, and game can be found at EV Analytics.

Note: Expected Value is a measure of how good a bet is, factoring the probability that it will win versus the odds the book is providing. If you were to wager $1.00 100 times on a bet with an Expected Value of $25, you would win some and you would lose some, but in the end you would expect to come away with $25 in profit on your $100 investment.

Saturday's top home run prop bets

Kyle Isbel | OVER 0.5 HR (+1400)
Projection: 8% chance of this bet hitting, with a $23.00 EV
One reason to bet this: The Minnesota Twins have just one same-handed RP in their bullpen, so Kyle Isbel can likely count on holding the platoon advantage against every reliever all game.

Drake Baldwin | OVER 0.5 HR (+900)
Projection: 11% chance of this bet hitting, with a $11.20 EV
One reason to bet this: The fifth-shallowest centerfield dimensions among all parks are found in Truist Park.

Jake Meyers | OVER 0.5 HR (+1200)
Projection:
9% chance of this bet hitting, with a $10.63 EV
One reason to bet this: The Minute Maid Park roof projects to be closed today, making weather conditions in this match-up 5 degrees hotter than the average outdoor game of all games on the slate today - favorable for offense.

Saturday's top pitcher prop bets

Hunter Dobbins | UNDER 4.5 K (-125)
Projection: 71% chance of this bet hitting, with a $35.07 EV
One reason to bet this: Fenway Park projects as the No. 26 venue in baseball for strikeouts, via my projections.

Tony Gonsolin | UNDER 4.5 K (+105)
Projection:
58% chance of this bet hitting, with a $19.21 EV
One reason to bet this: Considering that flyball hitters have a notable advantage over groundball pitchers, Tony Gonsolin and his 36.6% underlying GB% (via my projections) will be in a troublesome spot today being matched up with two opposing GB hitters.

Max Fried | UNDER 6.5 K (-115)
Projection: 62% chance of this bet hitting, with a $19.22 EV
One reason to bet this: As far as temperature and humidity go, the fourth-most suitable hitting weather on the schedule is expected for this matchup.
