Best MLB Triples Matchups — Monday, August 3, 2026
Top triples spot: Jake McCarthy
Jake McCarthy (COL) tops the board at 100, facing LHP Ian Seymour. The lefty is running the bases at .033 3B/PA against lefties this year — and .056 over the last two weeks, an elite bat that turns into a triple in about 2% of his trips. And Ian Seymour has been tough to triple against lefties lately — .000 triples 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. No real history against Ian Seymour. It all sets up in a hitter's park.
The rest of the top of the board
- Corbin Carroll (AZ) (90) vs RHP Michael King: an elite bat at .023 into an arm tough to triple against the same side (.000).
- Chandler Simpson (TB) (74) vs RHP Michael Lorenzen: a strong bat at .006 into an arm vulnerable to the gaps against the same side (.042), hitter's park.
- Pete Crow-Armstrong (CHC) (65) vs RHP the starter: an elite bat at .015 into an arm with little track record against the same side.
- Brandon Nimmo (TEX) (62) vs RHP Logan Webb: a strong bat at .006 into an arm vulnerable to the gaps against the same side (.046).
- Daylen Lile (WSH) (61) vs RHP Aaron Nola: an elite bat at .014 into an arm tough to triple against the same side (.000).

- Jonathan Aranda (TB) (58) vs RHP Michael Lorenzen: a station-to-station bat at .001 into an arm vulnerable to the gaps against the same side (.042), hitter's park.

Lineup watch
144 of today's hitters are still on projected lineups, drawn from each team's last game. Batting order drives the score, so these flip the moment official lineups post — usually about two hours before first pitch. Anyone who doesn't make the official card gets flagged "Not starting" and drops to the bottom.
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.
