Best MLB Singles Matchups — Wednesday, August 12, 2026
Top singles spot: Jake Mangum
Jake Mangum (PIT) tops the board at 100, facing RHP Janson Junk. The lefty is lining singles at .214 1B/PA against righties this year — and .159 over the last two weeks, an excellent bat that turns into a single in about 18% of his trips. And Janson Junk has been getting picked apart by righties lately — .174 singles per batter faced. One catch: the bullpen behind him has been stingy to that side late. He's hitting in a spot worth about 4.7 trips, so the volume's there. No real history against Janson Junk. It all sets up in a neutral park.

- Freddie Freeman (LAD) (100) vs LHP Daniel Lynch IV: an elite bat at .204 into an arm getting picked apart by the same side (.200).

How to read these singles matchups
Each score (0–100) starts with the hitter's singles 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.
