Check out the video above to see Tommy's baseball skills in action.
Tommy was born without most of his left arm, but that has not stopped him from hitting home runs for his Little League team, the St. Louis Cardinals, or from having batting practice against a retiree from the Major Leagues.
Just one week prior to the game, Tommy spent the day with the big St. Louis Cardinals and went up against former ace Chris Carpenter for batting practice.
His all-star swing doesn't just hit home runs - it whips golf balls down the green, too.
At age 3, Tommy was deemed a golf prodigy and appeared on the Ellen DeGeneres Show as well as Fox Sports with Tiger Woods.
