Best MLB Total Bases Matchups — Thursday, May 21, 2026
Top total bases spot: Ketel Marte
Ketel Marte (AZ) tops the board at 100, facing RHP Zach Agnos. The lefty is racking up bases at — TB/PA against righties this year, a solid bat that turns into a total base in about 37% of his trips. And Zach Agnos 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 .200 in 5 career PA against Zach Agnos, 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 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.
