Best MLB Walks Matchups — Saturday, May 30, 2026
Top walks spot: Jake McCarthy
Jake McCarthy (COL) tops the board at 100, facing RHP Adrian Houser. The lefty is working counts at — BB/PA against righties this year, a solid bat that turns into a walk in about 9% of his trips. And Adrian Houser has been thin against righties lately. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.7 trips, so the volume's there. He's owned Adrian Houser too — .400 across 5 career trips. It all sets up in a hitter's park, weather helping.
The rest of the top of the board
- Willy Adames (SF) (100) vs RHP Ryan Feltner: a solid bat at .085 into an arm with little track record against the same side, hitter's park.

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