Best MLB Walks Matchups — Tuesday, June 23, 2026
Top walks spot: Iván Herrera
Iván Herrera (STL) tops the board at 100, facing LHP Eduardo Rodriguez. The righty is working counts at .202 BB/PA against lefties this year — and .263 over the last two weeks, an excellent bat that turns into a walk in about 15% of his trips. And Eduardo Rodriguez has been handing out free passes to lefties lately — .189 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. No real history against Eduardo Rodriguez. It all sets up in a neutral park, though the weather fights it.
The rest of the top of the board
- Juan Soto (NYM) (100) vs RHP Edward Cabrera: an elite bat at .164 into an arm prone to walking the same side (.097), hot bat.
- Taylor Ward (BAL) (100) vs RHP Ryan Johnson: an excellent bat at .121 into an arm around league average against the same side (.091).
- Geraldo Perdomo (AZ) (96) vs RHP Kyle Leahy: an elite bat at .158 into an arm tough to walk against the same side (.043).
- Gunnar Henderson (BAL) (94) vs RHP Ryan Johnson: a strong bat at .105 into an arm tough to walk against the same side (.000).
- JJ Bleday (CIN) (90) vs RHP Brandon Sproat: an excellent bat at .124 into an arm handing out free passes to the same side (.130), due to bounce back.
- Pete Alonso (BAL) (87) vs RHP Ryan Johnson: a strong bat at .114 into an arm around league average against the same side (.091).
- Nathaniel Lowe (CIN) (83) vs RHP Brandon Sproat: an excellent bat at .130 into an arm handing out free passes to the same side (.130), due to bounce back.

How it played out
5 of the top 10 walks matchups landed at least one walk. Top play Iván Herrera 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.
