OK, imagine you're the plate umpire and here is the situation:
 Runners at 1st and 3rd, 2 out
 2 ball, 2 strike count on the batter
 Pitch comes in the strike zone
 Batter steps towards the plate while swinging the bat
 Ball misses the bat, hits the batter in the belly
 Ball then bounces from the batter's belly to the catcher, who catches the ball cleanly.
