Best MLB Stolen Bases Matchups — Tuesday, June 30, 2026
Top stolen bases spot: Esteury Ruiz
Esteury Ruiz (MIA) tops the board at 100, facing RHP Tanner Gordon. The righty is running at .167 SB/PA against righties this year — and .167 over the last two weeks, an elite bat that turns into a stolen base in about 7% of his trips. He's hitting in a spot worth about 4.5 trips, so the volume's there. No real history against Tanner Gordon. It all sets up in a hitter's park.

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 stolen bases matchups
Each score (0–100) starts with the hitter's stolen bases 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.
