MLB Strikeout Props Today September 17th, 2026: Best Pitcher K Picks, Predictions & Odds
Thursday's slate is topped by the Twins' strikeout leader chasing 200 punchouts against baseball's worst team, while a Brewers lefty coming off a disastrous relief appearance and a Tigers ground-ball specialist both project for the under. The fade of the day involves a Phillies veteran who has genuinely turned his season around, but is running into a Mets lineup that has stopped striking out over the last two weeks. For the full up-to-the-minute board, run these matchups through our Daily Strikeout Prop Finder and shop the market with our MLB Odds Finder before locking anything in. Let's get into today's best MLB strikeout picks.
Best MLB Strikeout Props Today
Taj Bradley Over 6.5 Strikeouts (-125)
Bradley sits just 10 strikeouts shy of 200 for the season, backing an 11-6 record and 3.81 ERA with a sharp .217 opponents' batting average across 165.1 innings. His last outing produced six scoreless innings against Cleveland on just one hit, and he already owns a 1-0 record with a 2.95 ERA in three career appearances against Los Angeles, including six strikeouts in his lone start against this exact opponent. Los Angeles carries a 25.8 percent strikeout rate against right-handed pitching for the season that has climbed to an elite 29.8 percent over the last two weeks, one of the best matchup numbers on the entire board, and the Angels are trying to avoid becoming the first 100-loss team in franchise history. That combination of a proven track record against this opponent and a genuinely elite, trending-hotter matchup gives him a clear path to clearing this number. Lock it in.
Kyle Harrison Under 5.5 Strikeouts (-145)
Harrison's last outing was a disaster, as he was charged with four earned runs on four hits without recording a single out in relief against Cincinnati, an alarming appearance that comes on the heels of a stretch of forearm tightness that sidelined him for roughly two months mid-season. He is being moved back into a starting role for this series finale after the Brewers shuffled their rotation following their NL Central clinch, adding real uncertainty about both his workload and his sharpness in his first true start back. Pittsburgh's strikeout rate against left-handed pitching has cooled sharply to just 16.7 percent over the last two weeks, down from a 25.3 percent season mark, one of the more significant recent dips on the entire board. That combination of a genuinely worrying last appearance and a cooling opponent makes the under the smarter side of this number. Take the under.
Framber Valdez Under 4.5 Strikeouts (-110)
Valdez has been dominant on the scoreboard lately, throwing 13 consecutive scoreless innings across his last two starts against Cleveland and Colorado, but his game has always been built around one of the best ground-ball rates in baseball rather than swing-and-miss stuff, reflected in a modest 17.0 percent strikeout rate and 6.7 K/9 on the season. He owns a 5-4 record with a 3.25 ERA in 11 career appearances against Chicago, and his most recent look at this exact opponent back in May produced just four strikeouts across 6.2 innings despite the White Sox scoring four runs. Chicago carries a 24.9 percent strikeout rate against left-handed pitching for the season, a number that on paper suggests upside, but Valdez's sinker-heavy approach has consistently generated quick groundball outs rather than empty swings even during his best recent stretches. That combination of a genuinely contact-oriented profile and a modest season-long strikeout baseline makes the under the smarter side of this number. Take the under.

Strikeout Props to Avoid Today
Aaron Nola vs Mets
Nola has genuinely turned his season around, posting a 2.47 ERA and 1.18 WHIP over his last eight outings after a rough first several months that left his overall line at 6-10 with a 4.69 ERA. The complication tonight is the opponent, since New York's strikeout rate against right-handed pitching has fallen to just 16.8 percent over the last two weeks, a steep drop from a 22.2 percent season mark and one of the more significant recent declines on the entire board. Nolan McLean has also owned this Phillies lineup throughout his career, adding to the sense that Philadelphia's offense could be pressing rather than driving deep counts tonight, which historically has meant quicker outs rather than swings and misses against Nola specifically. Even a pitcher performing at his best over the last two months can run into trouble missing bats against a lineup that has simply stopped striking out lately, and that combination of a genuinely cooling opponent makes clearing this number a tougher ask than his recent run prevention suggests. Leave it alone.
