How is the rbis matchup score calculated?

His rate of driving runs in against that hand comes first, weighted to recent form. Then the piece that's unique to this board: who bats in front of him and how often they're on base when he comes up. The bullpen, park and weather finish it. 0–100 across the slate.

What does RBI/PA mean?

It's the share of a hitter's trips to the plate that drive in a run. Around .105 is league average. RBIs lean on lineup spot and who's on base ahead of you, so we weigh the matchup but it's a noisier market than hits.

What does the score actually mean?

Higher is better. RBI is the most situation-dependent number on the site — a great bat batting eighth behind three automatic outs will grade below a lesser bat hitting fourth. That's the board working, not a bug.

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 RBI.

What is a platoon split (handedness split)?

The handedness gap matters here, but so does what's happening in front of him. A hitter's rate against the hand he's facing sets the baseline; the guys on base ahead of him decide whether it turns into a run driven in.

What are park factors?

Parks move RBI through the hits that produce them. A yard where balls fall in and fly out keeps innings alive and puts more men on for the middle of the order. 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 RBI 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 rbis 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+ RBI" 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. RBI is noisier than the contact boards because it depends on traffic ahead of him, so judge this one over a longer run — the season hit rate is on the board and every past date is auditable.

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?
