Best MLB Walks Matchups — Tuesday, July 28, 2026
Top walks spot: Geraldo Perdomo
Geraldo Perdomo (AZ) tops the board at 100, facing RHP Bubba Chandler. The lefty is working counts at .165 BB/PA against righties this year — and .303 over the last two weeks, an elite bat that turns into a walk in about 16% of his trips. And Bubba Chandler has been fairly stingy with walks against righties lately — .071 walks per batter faced. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's just .000 in 3 career PA against Bubba Chandler, 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
- Ronald Acuña Jr. (ATL) (89) vs RHP Christian Scott: an excellent bat at .133 into an arm tough to walk against the same side (.059).
- Brice Turang (MIL) (89) vs RHP Landen Roupp: an excellent bat at .122 into an arm around league average against the same side (.091).
- Willson Contreras (BOS) (81) vs LHP Gage Jump: an excellent bat at .125 into an arm handing out free passes to the same side (.188), due to bounce back.

Lineup watch
270 of today's hitters are still on projected lineups, drawn from each team's last game. Batting order drives the score, so these flip the moment official lineups post — usually about two hours before first pitch. Anyone who doesn't make the official card gets flagged "Not starting" and drops to the bottom.
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.
