Best MLB Runs Matchups — Sunday, September 20, 2026
Top runs spot: Pete Crow-Armstrong
Pete Crow-Armstrong (CHC) tops the board at 100, facing RHP Rhett Lowder. The lefty is scoring at .182 R/PA against righties this year — and .268 over the last two weeks, an excellent bat that turns into a run in about 16% of his trips. And Rhett Lowder has been getting lit up by righties lately — .163 runs per batter faced. The bullpen behind him hasn't been any better to that side, so there's no relief late. He's hitting in a spot worth about 4.7 trips, so the volume's there. He's just .143 in 7 career PA against Rhett Lowder, but that's a tiny sample and the matchup says regression. It all sets up in a neutral park.
The rest of the top of the board
- Randy Arozarena (SEA) (91) vs RHP Tomoyuki Sugano: a strong bat at .146 into an arm getting lit up by the same side (.348), hot bat.
- Jose Siri (LAA) (82) vs RHP Dean Kremer: a strong bat at .149 into an arm stingy with runs against the same side (.077).
- Ben Rice (NYY) (81) vs RHP Corbin Burnes: an excellent bat at .151 into an arm mostly holding up against the same side (.111).
- Zach Neto (LAA) (80) vs RHP Dean Kremer: a strong bat at .135 into an arm stingy with runs against the same side (.077), due to bounce back.
- Seiya Suzuki (CHC) (78) vs RHP Rhett Lowder: a strong bat at .139 into an arm getting lit up by the same side (.476).
- Steven Kwan (CLE) (78) vs RHP Jack Perkins: a solid bat at .127 into an arm stingy with runs against the same side (.071).

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 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 — the WizLine 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.
