Best MLB Walks Matchups — Tuesday, September 15, 2026
Top walks spot: Juan Soto
Juan Soto (NYM) tops the board at 100, facing RHP Shane Baz. The lefty is working counts at .194 BB/PA against righties this year — and .146 over the last two weeks, an elite bat that turns into a walk in about 17% of his trips. And Shane Baz has been fairly stingy with walks against righties lately — .073 walks per batter faced. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's owned Shane Baz too — .375 across 8 career trips. It all sets up in a neutral park.
The rest of the top of the board
- Seiya Suzuki (CHC) (100) vs LHP Martín Pérez: an elite bat at .156 into an arm handing out free passes to the same side (.156).
- Jake Bauers (MIL) (96) vs RHP Lake Bachar: an elite bat at .163 into an arm handing out free passes to the same side (.182).
- Kevin McGonigle (DET) (91) vs RHP Braydon Fisher: an excellent bat at .133 into an arm handing out free passes to the same side (.167).
- Yordan Alvarez (HOU) (90) vs RHP Michael Wacha: an elite bat at .160 into an arm fairly stingy with walks against the same side (.080), due to bounce back.
- J.P. Crawford (SEA) (83) vs RHP Ryan Johnson: an excellent bat at .124 into an arm prone to walking the same side (.100).
- Brice Turang (MIL) (83) vs RHP Lake Bachar: an excellent bat at .134 into an arm handing out free passes to the same side (.182).

Lineup watch
270 of today's hitters are still on projected lineups, drawn from each team's last game. Batting order drives the score, so these flip the moment official lineups post — usually about two hours before first pitch. Anyone who doesn't make the official card gets flagged "Not starting" and drops to the bottom.
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.
