Best MLB Walks Matchups — Monday, June 29, 2026
Top walks spot: Juan Soto
Juan Soto (NYM) tops the board at 100, facing RHP Trey Yesavage. The lefty is working counts at .167 BB/PA against righties this year — and .212 over the last two weeks, an excellent bat that turns into a walk in about 15% of his trips. And Trey Yesavage has been handing out free passes to righties lately — .118 walks per batter faced. The bullpen behind him hasn't been any better to that side, so there's no relief late. He's hitting in a spot worth about 4.5 trips, so the volume's there. No real history against Trey Yesavage. It all sets up in a neutral park.
The rest of the top of the board
- Yordan Alvarez (HOU) (86) vs RHP Zebby Matthews: an elite bat at .156 into an arm tough to walk against the same side (.035), due to bounce back.
- Michael Busch (CHC) (78) vs RHP the starter: an excellent bat at .142 into an arm with little track record against the same side.
- Geraldo Perdomo (AZ) (78) vs RHP Tyler Mahle: an excellent bat at .142 into an arm tough to walk against the same side (.000).

Lineup watch
234 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.
