'Robot umpires' debuted in the Atlantic League All-Star game, here's what happened. Interesting experiment. Not sure how this will work out, but it shows the willingness to try new concepts. Note that the umpire has the ability to override the "robot" ball/strike call - and the human umpire still calls check-swings. This has a chance of working. The idea of "stealing first base" on a wild pitch or passed ball seems a bit more weird - but again, they're willing to experiment.
