Best MLB Walks Matchups — Thursday, September 17, 2026
Top walks spot: Juan Soto
Juan Soto (NYM) tops the board at 100, facing RHP Aaron Nola. The lefty is working counts at .194 BB/PA against righties this year — and .159 over the last two weeks, an elite bat that turns into a walk in about 17% of his trips. And Aaron Nola has been prone to walking righties lately — .103 walks per batter faced. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's just .194 in 62 career PA against Aaron Nola, but that's a tiny sample and the matchup says regression. It all sets up in a neutral park.
The rest of the top of the board
- Mike Trout (LAA) (100) vs RHP Taj Bradley: an elite bat at .152 into an arm tough to walk against the same side (.000), due to bounce back.
- Kevin McGonigle (DET) (100) vs RHP Erick Fedde: an excellent bat at .143 into an arm tough to walk against the same side (.048).
- Yordan Alvarez (HOU) (91) vs RHP Seth Lugo: an elite bat at .155 into an arm handing out free passes to the same side (.160).
- Brice Turang (MIL) (88) vs RHP Wilber Dotel: an excellent bat at .142 into an arm with little track record against the same side.
- Munetaka Murakami (CWS) (82) vs LHP Framber Valdez: an elite bat at .150 into an arm tough to walk against the same side (.000), due to bounce back.
- Bryce Harper (PHI) (78) vs RHP Nolan McLean: an excellent bat at .139 into an arm fairly stingy with walks against the same side (.081).
- Kyle Schwarber (PHI) (77) vs RHP Nolan McLean: an excellent bat at .129 into an arm fairly stingy with walks against the same side (.081).

How it played out
6 of the top 10 walks matchups landed at least one walk. Top play Juan Soto finished with 2 walks. We post the result next to every projection so you can grade the board yourself — and so the model gets re-tuned against what actually happened.
How to read these walks matchups
Each score (0–100) starts with the hitter's walks per plate appearance against the hand he's facing — weighted toward the last two weeks, then the season, then a two-year baseline. Then it layers in the bullpen, his spot in the order, and park and weather. Higher means more of it points his way. It's context, not a lock — a great spot still goes 0-for-4 sometimes, and a tough one runs into one. The edge is in stacking the odds, and since we grade every board, you can see how often the top of the list delivers.
What the walks board is
The Walks board projects the chance a hitter draws a walk. One statistical model scores every matchup on the slate the same way — a star and a backup judged on the matchup in front of them, not their name — and every number is graded against the real box score once the games go final.
How the model gets its number
It isn't a gut call or a name game. The projection is built from a few things:
- His plate discipline.
- The pitcher's control.
- The count leverage in the matchup.
Those pieces combine into one number, and the model re-tunes itself weekly against how its past calls actually landed.
