Common questions

Do MLB umpires really affect the score?

The numbers on this page are real averages from logged games, shown next to the league average so you can see the gap. Some of the gap is the umpire, some is the games they happen to get. Treat it as one more thing to check — not a system on its own.

Where does this data come from?

Official game records: final scores, pitch-by-pitch accuracy tracking for every logged game each umpire worked. We only publish a full page for umpires with enough games to be meaningful.

How do bettors use umpire stats?

Mostly for totals. If a umpire's games run clearly above or below the league average, that's worth knowing before you take an over or under. Check the number, then check the price.
