Best MLB Triples Matchups — Thursday, August 27, 2026
Top triples spot: Corbin Carroll
Corbin Carroll (AZ) tops the board at 100, facing RHP Landen Roupp. The lefty is running the bases at .024 3B/PA against righties this year — and .035 over the last two weeks, an elite bat that turns into a triple in about 2% of his trips. And Landen Roupp has been vulnerable to the gaps against righties lately — .022 triples 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 4.5 trips, so the volume's there. He's just .182 in 11 career PA against Landen Roupp, but that's a tiny sample and the matchup says regression. It all sets up in a park that leans hitter.
The rest of the top of the board

Lineup watch
126 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.
