As expected, MLB today announced it will begin using instant replay for “boundary calls”–basically, wether or not home runs were fair or foul, interfered with, or went over the wall at all. The unexpected part is that the new system begins… Thursday. (Wire story here, more detailed MLB.com story here)
Not during spring training, not to be tested during the Arizona Fall League, not put in place over the All-Star break… Thursday. Right in the middle of the season. It’s unclear to me from these stories how much testing has taken place. I hope it’s a least a little bit, because starting something like this on a random day in the middle of the season seems, well, like something only MLB would do.
