How is the doubles matchup score calculated?

It's his doubles rate against that hand with recent form counting most, over a two-year baseline. Then gap dimensions, the opposing bullpen, and his expected trips from the order. 0–100 across the slate.

What does 2B/PA mean?

Doubles per plate appearance — how often a hitter reaches second on his own hit. Around .042 (about one every 24 trips) is league average. Ballpark matters more here than on most boards: deep gaps and high walls turn would-be outs and home runs into doubles.

What does the score actually mean?

Higher is better. Doubles are a thin, streaky stat, so read the confidence meter next to the score more carefully here than on the hits board.

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 double.

What is a platoon split (handedness split)?

Doubles sit between contact and power, and so does the split. The opposite hand means more balls driven into the gap rather than rolled over — the exact batted ball this board is looking for.

What are park factors?

Gap size is everything for two-baggers. A deep alley and a high wall keep balls in play and let a runner take second; a short porch turns the same swing into a home run instead. Above 1.00 bumps the score, below 1.00 trims it.

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 double 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 doubles 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+ double" 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 the box score. Doubles are streaky and the samples are thin, so read this board's record over a season rather than a week — it's posted, and every past date rolls back.

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.

Is MatchWiz free?
