Best MLB Walks Matchups — Wednesday, August 19, 2026
Top walks spot: Yordan Alvarez
Yordan Alvarez (HOU) tops the board at 100, facing RHP Walbert Ureña. The lefty is working counts at .181 BB/PA against righties this year — and .143 over the last two weeks, an excellent bat that turns into a walk in about 14% of his trips. And Walbert Ureña has been handing out free passes to righties lately — .182 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 a fine .286 in 7 career PA against Walbert Ureña. It all sets up in a neutral park.

- Cole Carrigg (COL) (100) vs RHP Roki Sasaki: a strong bat at .114 into an arm tough to walk against the same side (.040).

How it played out
4 of the top 10 walks matchups landed at least one walk. Top play Yordan Alvarez 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.
