How is the singles matchup score calculated?

It's his singles-per-trip rate against that hand, weighted to the last two weeks, then the season, then two years. Contact quality drives it, not power. Then the opposing bullpen, his spot in the order, and the park. 0–100 across the slate.

What does 1B/PA mean?

Singles per plate appearance — how often a hitter gets a one-base hit. Around .14 (roughly one every seven trips) is league average. It rewards contact hitters rather than sluggers: a single is the most common hit in baseball, so this board tends to favour high-average bats over power.

What does the score actually mean?

Higher is better. This board deliberately favours high-average contact bats over sluggers — a single is the most common hit in baseball, and the guys who collect them aren't usually the guys hitting 40 homers.

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 single.

What is a platoon split (handedness split)?

On a singles board the split is about contact quality, not power. Facing the opposite hand, a hitter sees the ball longer and puts more balls in play — which is the whole job here. Slug barely enters into it.

What are park factors?

Singles live in the gaps and on the turf. Fast infields, big outfields, and deep foul ground all move the number. 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 single 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 singles 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+ single" 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. Singles are the most common hit in baseball, so this board's top end is more predictable than the power boards — and the posted season rate is there to check.

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?

Yes. The full board, every game page, and the daily archive are free, no login. Best-price odds and the betting tools are the paid tier.
