Isn’t it obvious that baseball should have it? Maybe not in the regular season, when bad calls can even out over 162 games. But in the post-season when they can loom so large. Give each teams two challenges a game that they can use on calls other than balls and strikes. Will this interrupt the flow of the game? Unfortunately, the game already has very little flow. Belated congrats, by the way, to the Astros and the White Sox–I’ve been too busy sulking to say anything.
