Best MLB Walks Matchups — Thursday, June 25, 2026
Top walks spot: Geraldo Perdomo
Geraldo Perdomo (AZ) tops the board at 100, facing RHP Michael McGreevy. The lefty is working counts at .157 BB/PA against righties this year — and .283 over the last two weeks, an elite bat that turns into a walk in about 16% of his trips. And Michael McGreevy has been tough to walk against righties lately — .067 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. No real history against Michael McGreevy. It all sets up in a neutral park, though the weather fights it.
The rest of the top of the board
- Nick Kurtz (ATH) (100) vs RHP Landen Roupp: an elite bat at .171 into an arm around league average against the same side (.087), due to bounce back.
- Kevin McGonigle (DET) (100) vs RHP Tatsuya Imai: an excellent bat at .145 into an arm tough to walk against the same side (.000).
- Michael Busch (CHC) (93) vs RHP Freddy Peralta: an excellent bat at .137 into an arm around league average against the same side (.091).
- Yordan Alvarez (HOU) (93) vs RHP Troy Melton: an elite bat at .152 into an arm around league average against the same side (.091).
- George Springer (TOR) (83) vs LHP MacKenzie Gore: an excellent bat at .122 into an arm around league average against the same side (.094).
- Bryce Harper (PHI) (74) vs RHP Cade Cavalli: an excellent bat at .132 into an arm fairly stingy with walks against the same side (.080).
- Ian Happ (CHC) (74) vs RHP Freddy Peralta: an excellent bat at .123 into an arm around league average against the same side (.091), hot bat.

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.
