The play didn't have an impact on the outcome of the Royals' wild 7-6 win at Boston on Tuesday, but this was one of the rarest plays you'll see in a game.
The Royals had runners on first and second with two outs and Lucas Duda at the plate. Boston catcher Christian Vazquez blocked a pitch from Carson Smith and the ball was on the ground next to him. Vazquez used his catcher's mask to secure the ball and that's not allowed.
Home plate umpire Chris Conroy was watching Vazquez and immediately made his ruling.
