Best MLB Singles Matchups — Monday, August 31, 2026
Top singles spot: Henry Bolte
Henry Bolte (ATH) tops the board at 100, facing RHP Jacob deGrom. The righty is lining singles at .197 1B/PA against righties this year — and .255 over the last two weeks, an elite bat that turns into a single in about 20% of his trips. And Jacob deGrom has been getting picked apart by righties lately — .267 singles per batter faced. 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. No real history against Jacob deGrom. It all sets up in a neutral park.

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.
