Best MLB Walks Matchups — Monday, June 29, 2026
Top walks spot: Juan Soto
Juan Soto (NYM) tops the board at 100, facing RHP Trey Yesavage. The lefty is working counts at .167 BB/PA against righties this year — and .212 over the last two weeks, an excellent bat that turns into a walk in about 15% of his trips. And Trey Yesavage has been handing out free passes to righties lately — .118 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. No real history against Trey Yesavage. It all sets up in a neutral park.
The rest of the top of the board
- Yordan Alvarez (HOU) (100) vs RHP Zebby Matthews: an elite bat at .156 into an arm tough to walk against the same side (.035), due to bounce back.
- Michael Busch (CHC) (100) vs RHP Griffin Canning: an excellent bat at .141 into an arm handing out free passes to the same side (.118).
- Geraldo Perdomo (AZ) (100) vs RHP Tyler Mahle: an excellent bat at .142 into an arm tough to walk against the same side (.000).
- Nick Kurtz (ATH) (95) vs LHP Eric Lauer: a strong bat at .107 into an arm handing out free passes to the same side (.250).
- Matt Chapman (SF) (88) vs LHP Eduardo Rodriguez: a strong bat at .113 into an arm handing out free passes to the same side (.125).
- Shohei Ohtani (LAD) (88) vs LHP Gage Jump: a solid bat at .090 into an arm handing out free passes to the same side (.167).
- Xavier Edwards (MIA) (86) vs LHP Sean Sullivan: a strong bat at .105 into an arm with little track record against the same side, hitter's park, hot bat.

How it played out
7 of the top 10 walks matchups landed at least one walk. Top play Juan Soto 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.
