Settle the strike-zone argument with data
You’ve seen the MLB umpire scorecards that go around after every big-league game. This is that, for your games. The generator takes every called pitch in your Trackman or Yakkertech file — swings don’t count, only the pitches the umpire actually ruled on — and compares its tracked location against the strike zone. Called strikes outside the zone and called balls inside it get flagged as misses.
The scorecard rolls it up into an overall accuracy percentage, missed-call counts in both directions, and a zone map plotting every decision from the game, so you can see at a glance whether the misses clustered on the outside corner or at the knees.
Coaches use it for post-game review and for keeping the dugout honest — “that zone was huge tonight” is a lot more useful as a plotted chart than as a complaint. And because it runs from the same game CSV as your pitching and framing reports, grading the zone costs you nothing extra: same file, one more report.
Common questions
How does the umpire scorecard decide a call was missed?
It plots every called ball and strike from the game file against the rulebook strike zone. A called strike outside the zone or a called ball inside it is flagged as a missed call, and the report tallies accuracy, missed calls by count and inning, and which side the zone favored.
What data do I need for a scorecard?
A Trackman or Yakkertech game CSV — it carries the pitch locations and ball/strike calls the scorecard is built from. A bullpen file won’t work, since there are no called pitches or umpire.
Can I print or share the scorecard?
Yes. Every scorecard is print-ready and can be downloaded as a PDF or shared as a link, so you can back up a conversation about the zone with objective data.
Does it show which team the zone favored?
Yes — the report breaks down missed calls and run impact by side, so you can see whether the zone leaned for or against your team on the night.
