Wednesday’s MLB slate is loaded with strikeout upside, and three pitchers in particular look primed to blow past their strikeout lines. Andrew Painter is finally putting his stuff back together in Philadelphia, Michael Wacha has quietly turned into a strikeout machine for a Royals team with nothing left to play for, and Foster Griffin has been one of the most underrated arms in the American League all season. Each of these situational spots offers real value once you dig into the recent form and the matchup.

None of this requires guesswork — the recent workloads and the opposing lineups line up cleanly. Here’s the breakdown on all three, plus how to build them into a card at your book.

Andrew Painter Over 4.5 Strikeouts vs. Houston

Andrew Painter has been erratic across his rookie campaign, but his swing-and-miss stuff has never been the issue — his 7.78 K/9 this season tells that story on its own. What matters for Wednesday is the recent stretch: across his last three starts, Painter has struck out six, six, and eight batters, clearing the 4.5 mark comfortably in all three outings. That’s a pitcher who has settled in after his innings limit scares earlier in the year, and he’s doing it with swing-and-miss stuff that plays against almost any lineup.

The matchup only helps his case. Houston’s offense has been a shell of its usual self this year, hitting .240 as a team with a .722 OPS — well below the free-swinging, contact-first Astros lineups of years past. Yordan Alvarez is still a load in the middle of the order, but names like Jose Altuve, Christian Walker, and Cam Smith have all struck out at elevated rates in 2026. A rookie righty with a fastball that touches the mid-90s and a power breaking ball is exactly the type of matchup this Houston lineup has struggled against all season.

Michael Wacha Over 3.5 Strikeouts vs. Arizona

Michael Wacha isn’t the guy who racks up double-digit strikeout totals, but his floor has been remarkably steady, and that’s exactly what makes an Over 3.5 number attractive. Across his last three starts, Wacha has struck out seven, ten, and six batters — an average of 7.67 per outing — while sitting at a 7.28 K/9 for the season. A line at 3.5 isn’t asking him to have his best game; it’s asking him to have roughly half of what he’s already been doing on a start-to-start basis.

Wacha draws Arizona on Wednesday, and while the Diamondbacks have a respectable offense overall, they haven’t been immune to strikeout-prone stretches against pitchers who can locate a changeup down in the zone — which has long been Wacha’s bread-and-butter weapon. With a soft line like this relative to his actual recent output, the number looks like it hasn’t fully caught up to how consistently he’s missing bats right now.

Foster Griffin’s Strikeout Prop vs. Baltimore

Foster Griffin has quietly had one of the better seasons of any starting pitcher who doesn’t get much national attention. He sits at 15-4 with a 3.26 ERA and 142 strikeouts across 160.1 innings — numbers that would headline most rotations, let alone come from a pitcher operating largely under the radar in Cleveland. His recent form has stayed strong, and he’s shown the ability to consistently miss bats deep into games rather than just piling up strikeouts in short outings.

Wednesday’s matchup against Baltimore lines up well. The Orioles counter with Shane Baz, and while this game has drawn attention for its pitching matchup on both sides, Griffin has the swing-and-miss secondary stuff — a changeup and a breaking ball he commands well from the left side — to work through Baltimore’s order multiple times. Given his season-long strikeout rate and the way he’s trending, his prop line represents good value against a Baltimore lineup that has had its share of strikeout-prone stretches this season.

Lock These In

All three of these strikeout props line up around the same theme: pitchers whose recent workloads have already been clearing these numbers with room to spare, against lineups that have shown real vulnerability to swing-and-miss stuff. Here’s the full card for Wednesday:

None of these require a leap of faith — just a look at what each pitcher has actually been doing over their last few turns through the rotation.
