Best MLB Runs Matchups — Wednesday, September 2, 2026
Top runs spot: Shohei Ohtani
Shohei Ohtani (LAD) tops the board at 100, facing LHP Brycen Mautz. The lefty is scoring at .140 R/PA against lefties this year — and .063 over the last two weeks, a solid bat that turns into a run in about 13% of his trips. And Brycen Mautz has been thin against lefties lately. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.7 trips, so the volume's there. No real history against Brycen Mautz. It all sets up in a neutral park.
The rest of the top of the board
- Paul Goldschmidt (NYY) (100) vs LHP Reid Detmers: a solid bat at .129 into an arm stingy with runs against the same side (.036).
- Jeremy Peña (HOU) (100) vs RHP Davis Martin: an excellent bat at .162 into an arm getting lit up by the same side (.571).
- Rafael Devers (SF) (95) vs RHP Bubba Chandler: a strong bat at .149 into an arm getting lit up by the same side (.182), hot bat.
- Kevin McGonigle (DET) (92) vs RHP Dean Kremer: a strong bat at .145 into an arm getting lit up by the same side (.320).
- Jackson Holliday (BAL) (85) vs RHP Tomoyuki Sugano: a solid bat at .126 into an arm getting lit up by the same side (.250).
- Iván Herrera (STL) (84) vs RHP Yoshinobu Yamamoto: a strong bat at .131 into an arm mostly holding up against the same side (.105).
- Bryce Harper (PHI) (84) vs RHP Taylor Clarke: an excellent bat at .157 into an arm getting lit up by the same side (.176).

How it played out
5 of the top 10 runs matchups landed at least one run. Top play Shohei Ohtani finished with 1 run. 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 runs matchups
Each score (0–100) starts with the hitter's runs scored 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 runs board is
The Runs board projects the chance a hitter scores a run. 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 on-base ability at the top of the order.
- The bats due up behind him.
- The opposing run-prevention.
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?
Like RBIs, runs is a lumpy market that grades efficient once you model the clustering honestly. Transparency board — our number set beside the line, graded.
How to use it
Useful context for top-of-the-order run creation, not a lean.
Everything here is a research signal from the model, graded in public — not betting advice, and no outcome is guaranteed.
