How is the walks matchup score calculated?

It's his walk rate against that hand, weighted to recent form over a two-year baseline, set against how freely that arm gives them up. Command and plate discipline carry this board; the park barely moves it. 0–100 across the slate.

What does BB/PA mean?

Walks per plate appearance — how often a hitter draws a base on balls. Around .085 (one walk every ~12 trips) is league average; .12+ is elite plate discipline. The matchup pairs the hitter's walk rate with how freely the pitcher gives them up.

What does the score actually mean?

Higher is better. This board rewards patience and punishes chase — a disciplined bat against a wild arm will out-grade a better hitter who swings at everything.

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 walk.

What is a platoon split (handedness split)?

Walk rates split by hand too, and often the other way round to what you'd expect — some hitters get more free passes against the same hand because the arm won't give in with the platoon disadvantage.

What are park factors?

Parks barely move walks, and the board reflects that. What matters is the arm's command and the umpire behind the plate, not the dimensions. Above 1.00 bumps the score, below 1.00 trims it — the swing is small here.

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 walk 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 walks 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+ walk" 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. Walks are among the most stable rates in baseball, so this board's record holds up better over short runs than the power boards — the season number is posted either way.

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?
