Best MLB Walks Matchups — Saturday, August 15, 2026
Top walks spot: Ben Rice
Ben Rice (NYY) tops the board at 100, facing RHP Braydon Fisher. The lefty is working counts at .150 BB/PA against righties this year — and .200 over the last two weeks, an excellent bat that turns into a walk in about 13% of his trips. And Braydon Fisher has been handing out free passes to righties lately — .389 walks per batter faced. The bullpen behind him hasn't been any better to that side, so there's no relief late. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's owned Braydon Fisher too — .333 across 3 career trips. It all sets up in a neutral park.
The rest of the top of the board
- Joc Pederson (TEX) (100) vs RHP J.T. Ginn: an excellent bat at .122 into an arm handing out free passes to the same side (.200), due to bounce back.
- Bryce Harper (PHI) (98) vs LHP Connor Prielipp: an elite bat at .162 into an arm handing out free passes to the same side (.222).
- Kyle Schwarber (PHI) (91) vs LHP Connor Prielipp: an excellent bat at .131 into an arm handing out free passes to the same side (.222).
- Trent Grisham (NYY) (87) vs RHP Braydon Fisher: a solid bat at .091 into an arm handing out free passes to the same side (.389), hot bat.
- Corey Seager (TEX) (82) vs RHP J.T. Ginn: a strong bat at .102 into an arm handing out free passes to the same side (.200), due to bounce back.
- Rafael Devers (SF) (77) vs RHP Michael Lorenzen: an excellent bat at .120 into an arm handing out free passes to the same side (.200).
- Lars Nootbaar (AZ) (76) vs RHP Grant Holmes: an excellent bat at .124 into an arm prone to walking the same side (.103).

How it played out
4 of the top 10 walks matchups landed at least one walk. Top play Ben Rice finished with 0 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.
