Last night, my batter was called out by the plate umpire after he swung at a 2-1 pitch and his follow-thru came into contact with the catcher's mitt and knocked the ball out of his glove.
As a former catcher, I remember getting clocked more than once on a batter's overswing. It was painful, but if it was "unintentional"...it was always a non-call. At best, it might be a dead-ball after the ball was knocked away from the catcher.
Any help or advice on this topic?
