Best MLB RBIs Matchups — Saturday, May 23, 2026
Top rbis spot: Sam Antonacci
Sam Antonacci (CWS) tops the board at 100, facing RHP Adrian Houser. The lefty is driving in runs at — RBI/PA against righties this year, a solid bat that turns into a RBI in about 11% of his trips. And Adrian Houser has been thin against righties lately. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.7 trips, so the volume's there. He's just .000 in 3 career PA against Adrian Houser, but that's a tiny sample and the matchup says regression. 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.
