Best MLB Doubles Matchups — Friday, August 7, 2026
Top doubles spot: Iván Herrera
Iván Herrera (STL) tops the board at 100, facing RHP Ryan Feltner. The righty is driving the ball at .043 2B/PA against righties this year — and .105 over the last two weeks, an excellent bat that turns into a double in about 6% of his trips. And Ryan Feltner has been getting squared up by righties lately — .105 doubles 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 4.3 trips, so the volume's there. He's just .200 in 5 career PA against Ryan Feltner, but that's a tiny sample and the matchup says regression. It all sets up in a neutral 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.
