Best MLB Doubles Matchups — Tuesday, August 4, 2026
Top doubles spot: Jake McCarthy
Jake McCarthy (COL) tops the board at 100, facing RHP Freddy Peralta. The lefty is driving the ball at .061 2B/PA against righties this year — and .053 over the last two weeks, a strong bat that turns into a double in about 5% of his trips. And Freddy Peralta has been getting squared up by righties lately — .240 doubles 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. He's just .100 in 10 career PA against Freddy Peralta, 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
- Corbin Carroll (AZ) (100) vs RHP Randy Vásquez: a strong bat at .051 into an arm getting squared up by the same side (.083), due to bounce back.

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