UNIQLO Field at Dodger Stadium is playing as hitter-friendly today (+3% triple park). Top bat there: Andy Pages (LAD) at 82. Angel Stadium is playing as hitter-friendly today (+3% triple park). Top bat there: Luis Lara (MIL) at 80. Petco Park is playing as hitter-friendly today (+3% triple park). Top bat there: Jung Hoo Lee (SF) at 79.

How is the triples matchup score calculated?

It's a weighted read of the hitter's triples per plate appearance against the hand he's facing — the last two weeks, the current season, and a two-year baseline, with recent form counting most. Then it folds in the opposing bullpen, his expected plate appearances from the batting order, and park and weather. Scores are set 0–100 across the day's slate, so the best matchup is always 100.

What does 3B/PA mean?

Triples per plate appearance — how often a hitter reaches third on his own hit. The league rate is about .004, or one every 250 trips, which makes the triple the rarest hit in baseball. Speed and ballpark do most of the work here, so treat this board as a projection of a rare event rather than a reliable edge.

What does the score actually mean?

Higher is better for the hitter. 80s and 90s mean the bat, the pitcher, and the park all line up. 40s and 50s mean it's neutral to tough. It's a ranking of how today's spots stack up against each other — not the odds of a triple.

What's the confidence meter?

It's how much data is behind the call — sample size on both the hitter and the pitcher, plus whether the lineup's official. A high score with low confidence is a thinner read than the same score backed by a deep track record. It's not a probability of a triple.

What is a platoon split (handedness split)?

Most hitters do better against the opposite hand — a lefty bat vs. a righty arm, and vice versa. That gap is the platoon split. The score leans hard on each hitter's rate against the hand he's facing today, which is why the same guy can rank very differently day to day.

What are park factors?

Parks aren't neutral. Dimensions, altitude, and weather make some easier to hit in than others. Above 1.00 bumps the score, below 1.00 trims it — same hitter, higher grade in a hitter's park than a pitcher's.

What do "2W", "SZN" and "2Y" mean?

The timeframes behind each rate: the last two weeks (recent form), the current season, and a trailing two years (a stable baseline). Recent form counts most, and small samples get pulled toward league average so a hot week doesn't fool the model.

What do "≈ est", "Due" and "Not starting" mean?

"≈ est" is a hitter we don't have splits for yet — a rookie or unmatched ID — shown at a league-baseline estimate instead of dropped. "Due" means he hasn't recorded a triple in a while and profiles for regression. "Not starting" means he was projected but didn't make the official lineup, so he slides to the bottom where you can still look him up.

Can I use this for triples props or DFS?

That's what it's built for — pre-slate research. The board surfaces which hitters have the best conditions today, and where one exists, we show the book's "1+ triple" line so you can shop the price. We're not a sportsbook and we don't post picks — we show the matchup data, the line, and the result. (Best-price and all-book odds are a Pro feature.)

How accurate is the model?

We grade every board against real results, and the top of the board lands a triple a lot more often than the slate as a whole. Weights get re-tuned weekly against actual outcomes on a held-out split, and since results sit next to projections, you can audit the hit rate yourself on any past date.

When do lineups update?

Projected lineups (marked "Proj") come from each team's last game. Official lineups usually drop about two hours before first pitch, and the board updates itself as they post. Batting order is a big driver, so it's worth a second look mid-afternoon — rankings shift as lineups lock.

Best MLB Triples Matchups — Friday, July 31, 2026

Corbin Carroll (AZ) is the top triples matchup on the Friday, July 31, 2026 board at 100, with Cole Young (SEA) and Kevin McGonigle (DET) right behind. Every hitter on the slate is ranked by triples upside — the arm and bullpen they face, batting order, park, and weather. It's the read DFS and prop players make before lock.

Top triples spot: Corbin Carroll

Corbin Carroll (AZ) tops the board at 100, facing RHP Tanner Bibee. The lefty is running the bases at .022 3B/PA against righties this year — and .049 over the last two weeks, an elite bat that turns into a triple in about 2% of his trips. And Tanner Bibee has been vulnerable to the gaps against righties lately — .029 triples per batter faced. 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 Tanner Bibee too — .500 across 6 career trips. It all sets up in a neutral park.

The rest of the top of the board

Cole Young (SEA) (99) vs RHP Zebby Matthews: an elite bat at .016 into an arm tough to triple against the same side (.000), hot bat.
Kevin McGonigle (DET) (91) vs LHP Jeffrey Springs: a league-average bat at .002 into an arm vulnerable to the gaps against the same side (1.000).
Lawrence Butler (ATH) (89) vs LHP Tyler Holton: an elite bat at .014 into an arm tough to triple against the same side (.000).
Riley Greene (DET) (86) vs LHP Jeffrey Springs: a league-average bat at .004 into an arm vulnerable to the gaps against the same side (1.000), due to bounce back.
Andy Pages (LAD) (82) vs LHP Ranger Suarez: an elite bat at .012 into an arm tough to triple against the same side (.000), hitter's park.
Kody Clemens (MIN) (80) vs RHP Bryce Miller: an elite bat at .012 into an arm tough to triple against the same side (.000).
Luis Lara (MIL) (80) vs RHP Ryan Johnson: an elite bat at .015 into an arm tough to triple against the same side (.000), hitter's park.

How it played out

0 of the top 10 triples matchups landed at least one triple. Top play Corbin Carroll finished with 0 triples. We post the result next to every projection so you can grade the board yourself — and so the model gets re-tuned against what actually happened.

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.
