Best MLB H+R+RBI Matchups — Tuesday, August 4, 2026
Top h+r+rbi spot: Jeremy Peña
Jeremy Peña (HOU) tops the board at 100, projected for about 0.47 H+R+RBI per plate appearance across 4.7 projected trips. We build the number bottom-up — summing his projection on every component board — so it moves with each of those matchups instead of a single rate, and inherits their tuning.

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 h+r+rbi matchups
Each score (0–100) starts with the hitter's combined hits + runs + 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.
