Whenever there's a tense moment in a baseball game that comes down to a final pitch, there's always the idea that the baseball pitcher will communicate to his catcher that he wants to throw in a fastball to swoop by the batter's stance and win the game, but today's baseball pitching actually includes more than one type of fastball in their pitching selection.  While some fastballs will roll in toward home plate at an extreme velocity simply because it's the fastest pitch a pitcher can handle, other fastballs are based on the breaking of movement or action within the pitch to achieve velocity.
