The robo-umps are coming

Not right away, but you can see it from here.

Computer plate umpires could be called up to the major leagues at some point during the next five seasons.

Umpires agreed to cooperate with Major League Baseball in the development and testing of an automated ball-strike system as part of a five-year labor contract announced Saturday, two people familiar with the deal told The Associated Press. The Major League Baseball Umpires Association also agreed to cooperate and assist if Commissioner Rob Manfred decides to utilize the system at the major league level. The people spoke on condition of anonymity because those details of the deal, which is subject to ratification by both sides, had not been announced.

The independent Atlantic League became the first American professional league to let a computer call balls and strikes at its All-Star Game on July 10. Plate umpire Brian deBrauwere wore an earpiece connected to an iPhone in his pocket and relayed the call upon receiving it from a TrackMan computer system that uses Doppler radar.

The Atlantic League experimented with the computer system during the second half of its season, and the Arizona Fall League of top prospects used it for a few dozen games this year at Salt River Fields.

MLB has discussed installing the system at the Class A Florida State League for 2020. If that test goes well, the computer umps could be used at Triple-A in 2021 as bugs are dealt with prior to a big league callup.

It is not clear whether the Major League Baseball Players Association would need to approve computerized ball and strikes.

“We are aware the umpires and MLB are in negotiations over a new CBA,” said players’ union head Tony Clark, a former All-Star first baseman. “MLB will have their negotiation with them, and they will need to discuss with us.”

See here for the background. Everyone agrees that robot umps are coming, at least for ball/strike calls, we’re all just arguing about the timeline. One of the things we’ve learned from the Atlantic League’s experience, is that the low-and-away part of the rulebook strike zone is generally not called a strike by human umpires but is by the robo-umps, and there’s a good argument that the automated system should be adjusted to be more like the human umps. Another thing we’ve learned is that accurate height data for the players is needed, else the automated zone, which is calculated based on those measurements, is not a true reflection of what it should be. There are still refinements to be made, and there’s no rush to get there. I’ll be a little surprised if we have this system in place in five years, but I’ll be even more surprised if we don’t in ten years.

    As a huge Buster Posey fan, I will miss catchers stealing strikes, which I believe is a craft. Nonetheless, I won’t miss Angel Hernandez and Joe West calling head scratchers. The umps will still determine swings and foul tips, so the robo umps only call taken pitches.
