Best MLB Total Bases Matchups — Sunday, July 19, 2026
Top total bases spot: Heriberto Hernández
Heriberto Hernández (MIA) tops the board at 100, facing LHP Robert Gasser. The righty is racking up bases at .505 TB/PA against lefties this year — and .938 over the last two weeks, a strong bat that turns into a total base in about 46% of his trips. And Robert Gasser has been getting squared up by lefties lately — .688 total bases per batter faced. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.5 trips, so the volume's there. No real history against Robert Gasser. It all sets up in a neutral park.

Lineup watch
279 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 total bases matchups
Each score (0–100) starts with the hitter's total 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.
