Johnny Flores Jr., reporting for Yahoo Sports, has a story about the future of baseball.

On Wednesday, the independent Atlantic League, which is a partner of Major League Baseball, debuted the electronic strike zone during its All-Star game, making it the first American professional league to do so.

Home plate umpire Brian deBrauwere wore an earpiece that was connected to an iPhone in his pocket. The earpiece relayed balls and strikes after receiving it from a TrackMan computer system utilizing a Doppler radar and deBrauwere called them as he received them.

It worked pretty flawlessly. I can’t wait for it to come to Major League Baseball.
