Best MLB Walks Matchups — Tuesday, July 21, 2026
Top walks spot: Mike Trout
Mike Trout (LAA) tops the board at 100, facing LHP Matthew Liberatore. The righty is working counts at .211 BB/PA against lefties this year — and .125 over the last two weeks, an elite bat that turns into a walk in about 15% of his trips. And Matthew Liberatore has been fairly stingy with walks against lefties lately — .077 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 4.5 trips, so the volume's there. He's owned Matthew Liberatore too — .333 across 3 career trips. It all sets up in a park that leans hitter, weather helping.
The rest of the top of the board
- James Wood (WSH) (100) vs RHP Michael Lorenzen: an elite bat at .171 into an arm handing out free passes to the same side (.143), hitter's park.
- Yordan Alvarez (HOU) (98) vs RHP Tyler Phillips: an elite bat at .159 into an arm prone to walking the same side (.095), hot bat.
- Alec Burleson (STL) (93) vs RHP Walbert Ureña: a solid bat at .093 into an arm handing out free passes to the same side (.455), hitter's park.
- Shea Langeliers (ATH) (92) vs LHP Kohl Drake: a league-average bat at .084 into an arm with little track record against the same side, hot bat.
- Lars Nootbaar (STL) (81) vs RHP Walbert Ureña: a strong bat at .118 into an arm handing out free passes to the same side (.455), hitter's park.
- Corbin Carroll (AZ) (81) vs RHP Jack Perkins: a strong bat at .115 into an arm handing out free passes to the same side (.143).
- Elly De La Cruz (CIN) (79) vs RHP Luis Castillo: a solid bat at .099 into an arm tough to walk against the same side (.000).

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