Best MLB RBIs Matchups — Sunday, June 21, 2026
Top rbis spot: Brandon Lowe
Brandon Lowe (PIT) tops the board at 100, facing RHP Michael Lorenzen. The lefty is driving in runs at .197 RBI/PA against righties this year — and .179 over the last two weeks, an excellent bat that turns into a RBI in about 16% of his trips. And Michael Lorenzen has been stingy with runs against righties lately — .095 RBIs 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. He's a fine .250 in 12 career PA against Michael Lorenzen. 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 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.
