Yorvit Torrealba let his temper get the better of him during a Venezuelan winter ball game Friday. Torrealba was upset with the home plate umpire's ball and strike calls and after swinging and missing for a third strike turned and began yelling at the ump from inches away. As he began to turn, he must have heard a response he didn't like and shoved him in the side of the head, making the ump stumble backwards. See the video after the jump (it's at about 00:58).
