Best MLB Walks Matchups — Friday, August 21, 2026
Top walks spot: Bryce Harper
Bryce Harper (PHI) tops the board at 100, facing RHP Hunter Dobbins. The lefty is working counts at .165 BB/PA against righties this year — and .286 over the last two weeks, an elite bat that turns into a walk in about 16% of his trips. And Hunter Dobbins has been handing out free passes to righties lately — .148 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 just .000 in 3 career PA against Hunter Dobbins, 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
- Shohei Ohtani (LAD) (100) vs RHP Bubba Chandler: a strong bat at .114 into an arm around league average against the same side (.087).
- Yordan Alvarez (HOU) (100) vs RHP J.T. Ginn: an excellent bat at .134 into an arm fairly stingy with walks against the same side (.077).
- Dominic Canzone (SEA) (92) vs LHP Matthew Boyd: a strong bat at .118 into an arm handing out free passes to the same side (.200), hot bat.
- Kyle Schwarber (PHI) (90) vs RHP Hunter Dobbins: an excellent bat at .126 into an arm handing out free passes to the same side (.148).
- Spencer Horwitz (PIT) (87) vs RHP Yoshinobu Yamamoto: a strong bat at .109 into an arm handing out free passes to the same side (.200).
- Jakob Marsee (MIA) (87) vs RHP Brad Lord: a strong bat at .113 into an arm handing out free passes to the same side (.444), due to bounce back.
- Freddie Freeman (LAD) (86) vs RHP Bubba Chandler: a solid bat at .098 into an arm around league average against the same side (.087).

How it played out
5 of the top 10 walks matchups landed at least one walk. Top play Bryce Harper finished with 1 walk. 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.
