Best MLB Walks Matchups — Thursday, July 30, 2026
Top walks spot: Fernando Tatis Jr.
Fernando Tatis Jr. (SD) tops the board at 100, facing LHP Robbie Ray. The righty is working counts at .120 BB/PA against lefties this year — and .214 over the last two weeks, a strong bat that turns into a walk in about 12% of his trips. And Robbie Ray has been around league average against lefties lately — .088 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 4.7 trips, so the volume's there. He's just .000 in 16 career PA against Robbie Ray, 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
- James Wood (WSH) (100) vs RHP Grant Holmes: an excellent bat at .145 into an arm handing out free passes to the same side (.182).
- Nick Kurtz (ATH) (98) vs RHP Sonny Gray: an excellent bat at .135 into an arm handing out free passes to the same side (.125), due to bounce back.

How it played out
5 of the top 10 walks matchups landed at least one walk. Top play Fernando Tatis Jr. 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.
