Today’s Top MLB Pitchers Strikeouts Prop Bets
Jack Flaherty – Under 6.5 Ks (-155)
Flaherty has pitched well this season with a good 1.25 K/IP rate, but today’s start versus the Astros is not an optimal matchup. Houston averages only 7.3 strikeouts per game, one of the lowest in all of MLB.
Flaherty had only 4 Ks in his recent start against the Milwaukee Brewers but had 4 Ks in his last game against the San Diego Padres. Under is the better side, and at -155, the implied probability is around 60.8% that it comes in.
Ronel Blanco – Over 5.5 Ks (-125)
Blanco’s strikeout stuff has performed well early in 2025, with 20 Ks over 23.1 innings. He faces Detroit now, a lineup whiffing 9.2 times a game—one of the highest in the league. Blanco had a 7-K performance against the Royals and 6 Ks against the Giants, and his stuff should hold here, too. At -125, the implied win probability is reasonable, and the matchup is a good value opportunity.
Dustin May – Over 5.5 Ks (-115)
May is still dealing with his swing-and-miss stuff, racking up 19 Ks in 22 innings thus far. Miami has swung and missed 8.7 times per game this season, a good number for over-bettors. May has hit 5.5 Ks twice in four starts, including a 5-strikeout effort in 5 innings last week. With May’s ability to earn strikeouts and a whiff-happy opponent, this line of -115 offers good value.
Bailey Ober – Under 5.5 Ks (-160) (Safest Choice)
Ober is a good control pitcher but not a top-end strikeout pitcher, with just 0.92 K/IP this season. Cleveland’s 7.43 strikeouts per game are near the bottom of baseball. Ober has fallen short of 6 Ks in 4 of his last 5 starts. At -160, this is the most secure bet on the board considering trends and opponents.
Griffin Canning – Over 4.5 Ks (-105) (Bold Prediction)
Canning has been consistent this season with a 1.0 K/IP rate, and he draws a Washington offense today that makes contact but hasn’t fared well lately vs. right-handed pitching. He has had 5+ strikeouts in 3 of 5 starts this season and has been sharp in his recent outings.
Although Washington only averages 7.9 strikeouts per game, Canning’s recent form and pitch count consistency make this a good aggressive play at close to even money.
