Best MLB Strikeout Props Today

Chris Sale Over 7.5 Strikeouts (-110)

Sale has been every bit the ace this season, backing 160 strikeouts and a 2.16 ERA across 129.2 innings with a 30.9 percent strikeout rate that ranks among the very best marks in baseball. His last meeting with Milwaukee this season produced a season-high 11 strikeouts over seven innings while allowing just one run, a dominant performance against this very opponent. Milwaukee carries a 22.6 percent strikeout rate against left-handed pitching, a solid number that plays into his slider-heavy approach even against one of the league's better lineups. That combination of proven history against this exact team and sustained excellence all season gives him a real path to clearing this number. Lock it in.

Reid Detmers Over 6.5 Strikeouts (+100)

Detmers has flashed real swing-and-miss ability all season, backing a 10.2 K/9 and a 3-6 record that undersells how well his stuff has played from outing to outing. His last start against Kansas City was one of his best, going seven innings with 11 strikeouts in a 1-0 Angels win, six of those punchouts coming on his slider alone. Texas carries a 23.9 percent strikeout rate against left-handed pitching, a favorable matchup for a pitcher who has shown he can dominate when his command is on. That blend of a strong recent outing and a strikeout-prone opponent makes this number very reachable. Get it in.

Connor Prielipp Over 5.5 Strikeouts (+126)

Prielipp has racked up 94 strikeouts across 87.2 innings this season, a 9.7 K/9 that reflects real bat-missing stuff even in a rookie campaign with rough overall results. His last outing against Philadelphia was ugly on the scoreboard, but volume of contact does not always mean a lack of swings and misses, and San Diego carries a 21.9 percent strikeout rate against left-handed pitching that offers a workable environment tonight. The Padres have been playing well as a team, winning seven of their last ten games, but that success has come more through disciplined contact than an inability to strike out against lefties specifically. His swing-and-miss upside combined with a fair matchup gives him a path to clearing this modest number. Get it in.

Sean Manaea Over 5.5 Strikeouts (-130)

Manaea has posted 113 strikeouts across 111.2 innings this season, a 9.2 K/9 that has helped the Mets win his last four starts even with a modest overall record. His last outing against Washington saw him work 6.1 innings and rack up strikeouts while managing traffic on the bases, a typical outing for his current form. Chicago carries a 24.7 percent strikeout rate against left-handed pitching, one of the more favorable matchups on today's board and a real boost for a pitcher who has been trending well of late. That combination of team success and a strong strikeout environment gives him a clear path to clearing this number. Lock it in.

Strikeout Props to Avoid Today

Logan Webb vs Red Sox

Webb has allowed just two runs across 20 innings this month, a strong recent stretch that has him pitching well even as his overall strikeout numbers stay modest with a 7.1 K/9 and 19.6 percent strikeout rate. The complete picture points elsewhere tonight, though, since his game is built entirely around inducing ground balls rather than swings and misses, reflected in just nine home runs allowed across 139.2 innings this season. Boston's strikeout rate against right-handed pitching has dropped to just 17.1 percent over the last two weeks, and the Red Sox have hit 13 home runs while slugging .445 over their last ten games, a hot, contact-first lineup at exactly the wrong time for a pitcher who lives off soft contact rather than punchouts. Even a well-pitched game from Webb is unlikely to produce a big strikeout total against a surging offense that has been squaring up mistakes rather than chasing his sinker. Leave it alone.
