Best MLB Doubles Matchups — Saturday, July 4, 2026
Top doubles spot: Willi Castro
Willi Castro (COL) tops the board at 100, facing LHP Robbie Ray. The righty is driving the ball at — 2B/PA against lefties this year, a solid bat that turns into a double in about 5% of his trips. And Robbie Ray has been thin against lefties lately. 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. He's owned Robbie Ray too — .333 across 6 career trips. It all sets up in a hitter's park, weather helping.

- Heliot Ramos (SF) (100) vs LHP Sean Sullivan: a solid bat at .045 into an arm with little track record against the same side, hitter's park.

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.
