Boston Red Sox ace Garrett Crochet headlines Friday night’s top MLB prop picks.
Today’s MLB props narrative: Crochet has been one of the best starters in baseball and I expect him to deliver in a crucial matchup against the rival Tampa Bay Rays.
Check out my top MLB prop bets for Sept. 19, featuring predictions on Geraldo Perdomo and Willy Adames.
MLB prop bets
Best bet: Crochet over 18.5 outs (+112)
The Red Sox ran through their bullpen this week during a three-game set vs. the Athletics.
On top of that, they’re fighting for a wild-card spot now that the Cleveland Guardians are surging behind them.
If Crochet is dealing — which is, of course, no guarantee — I have to imagine they’re going to ride him out. And Crochet deals more often than not. Even better, he consistently eats innings.
Crochet’s first season in Boston has been dynamite.
- First in MLB in Ks (240)
- Fifth in ERA (2.63)
- 10th in WHIP (1.05)
Crochet has thrown a career-high 191.1 innings, which leads the American League.
The hard-throwing southpaw has tossed six-plus innings in 23 of 30 starts.
Six innings won’t cash this — and coming back out for the seventh after sitting shouldn’t be taken lightly — but Crochet is consistently hovering around this number.
Crochet faced the Rays once this year and was spectacular, pitching a three-hit shutout with nine strikeouts.
Key stat: Crochet has cashed this bet 14 times.
Best MLB picks
Perdomo over 1.5 total bases (+125): The Arizona Diamondbacks should get to Philadelphia Phillies righty Taijuan Walker.
Perdomo, the club’s leadoff hitter, is as good a bet as any player to do damage. At -120 to score, I’m electing to play him on this prop instead.
- Perdomo is averaging 2.3 total bases over 15 games in September. During the month, he’s hitting a robust .327/.441/.618 with four homers.
- He’s batting .330 in the second half and ranks sixth in MLB in wRC+ over that stretch.
Walker has very little swing and miss ability and has been tattooed in four straight outings.
The veteran has surrendered four-plus runs each time out (7.65 ERA), allowing 32 hits and five homers over those 20 innings.
Adames 1+ RBI (+200): Adames has been a disappointment, but you can find things to like about his season. How about this:
- Since July 1, he’s fourth in the National League in RBI.
- He’s fourth in ISO over that same period and has a 140 wRC+.
Adames has pop and has been showing it following a miserable start to his San Francisco Giants tenure.
Locked in as the No. 3 hitter, Adames will hit behind two good bats when he sees Clayton Kershaw and the Los Angeles Dodgers tonight.
Kershaw has been a mixed bag this season and got drilled by the Giants at their pitcher-friendly park his last time out.
Tonight’s game is at hitter-friendly Dodger Stadium.
