Ump score

Great app considering these umpires are miscalling many pitches throughout the game. This app, well hopefully, will further motivate umpires to improve their performance, lessen any biases they may be having throughout the game and ultimately learn and be educated on their mistakes and weaknesses through the information and data given on this app. Thanks Mr. Williams for a brilliant idea and app.

Great Source of Insightful Baseball Analysis

The best data source for all things Umpire! I especially like the heat maps showing each Ump’s blind spots. This is a must have app for baseball and officiating aficionados!

Rock and rollllllllllllll ,

Great App

This is moneyball for umpiring. I have fun with this app and now watch baseball differently. Hopefully this app will effect positive change and umpiring improvements. Good stuff!
