Why ump.bot?
Umpires are human. Missed calls change games. We built the platform that holds every call accountable — after every game.
Our AI analyzes every pitch location against the batter's personalized strike zone, just like MLB's ABS system.
Get next-day umpire accuracy grades for every game. See which umps are sharp and which are struggling.
Full umpire accuracy database. Know what to expect before the first pitch — who favors pitchers, who squeezes.
How It Works
ump.bot processes pitch-tracking data after each game and compares every call against a batter-specific strike zone — the same methodology MLB uses for ABS.
We pull pitch-tracking data from every MLB game after it concludes.
Each pitch is measured against the batter's personalized strike zone.
We publish next-day scorecards, accuracy grades, and pitch-by-pitch missed-call breakdowns.
