Best MLB Triples Matchups — Saturday, August 15, 2026
Top triples spot: Michael Massey
Michael Massey (KC) tops the board at 100, facing LHP Reid Detmers. The lefty is running the bases at .013 3B/PA against lefties this year — and .083 over the last two weeks, an elite bat that turns into a triple in about 1% of his trips. And Reid Detmers has been tough to triple against lefties lately — .000 triples per batter faced. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.1 trips, so the volume's there. He's a fine .286 in 7 career PA against Reid Detmers. It all sets up in a park that leans hitter.

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