Automatic pitch calling instead of umpires. [View all]

Just a note about the relevance of umpires and the experiment of strike/ball detection/challenges by cameras.

In last nights All Star game 5 pitches were challenged, 4 were reversed. This is in some sense remarkably good. Good in that so few errors were made.

In the average Major League Baseball game an average of 290 pitches are thrown collectively.

4 errors is 1.37 percentage of 290. That is, while a single sample, remarkable. It shows just how good the umpires are, at least in this one game. A game that is being used to help determine whether or not to use cameras to challenge pitch calls.

I say hats off to the umpires and a bit of caution to those who want to insert machines into this process….careful of what you wish for.
