Best MLB RBIs Matchups — Sunday, June 21, 2026
Top rbis spot: Alec Bohm
Alec Bohm (PHI) tops the board at 100, facing LHP David Peterson. The righty is driving in runs at .191 RBI/PA against lefties this year — and .400 over the last two weeks, an elite bat that turns into a RBI in about 17% of his trips. And David Peterson has been getting lit up by lefties lately — .273 RBIs per batter faced. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.3 trips, so the volume's there. He's owned David Peterson too — .333 across 27 career trips. It all sets up in a neutral park, weather helping.

How to read these rbis matchups
Each score (0–100) starts with the hitter's RBIs 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.
