Best MLB Total Bases Matchups — Wednesday, August 12, 2026
Top total bases spot: Jac Caglianone
Jac Caglianone (KC) tops the board at 100, facing LHP Eric Lauer. The lefty is racking up bases at .430 TB/PA against lefties this year — and .579 over the last two weeks, a solid bat that turns into a total base in about 41% of his trips. And Eric Lauer has been getting squared up by lefties lately — .867 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. He's just .000 in 1 career PA against Eric Lauer, but that's a tiny sample and the matchup says regression. It all sets up in a neutral park.

How it played out
7 of the top 10 total bases matchups landed at least one total base. Top play Jac Caglianone finished with 1 total base. We post the result next to every projection so you can grade the board yourself — and so the model gets re-tuned against what actually happened.
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.
What the total bases board is
The Total Bases board projects how many bases a hitter racks up vs the posted total-bases line. One statistical model scores every matchup on the slate the same way — a star and a backup judged on the matchup in front of them, not their name — and every number is graded against the real box score once the games go final.
How the model gets its number
It isn't a gut call or a name game. The projection is built from a few things:
- His extra-base pop vs this arm.
- The park.
- Recent contact quality.
Those pieces combine into one number, and the model re-tunes itself weekly against how its past calls actually landed.
Is there a betting edge here?
