In one of the  oddest incidents ever witnessed in baseball, a star major league batter has been denied a home run after a pint-size fan snatched the ball from a fielder’s glove.

Arizona Diamondbacks slugger Tommy Pham stepped up to the plate and sent a towering short ro the wall, where Reds outfielder Spencer Steer timed his leap perfectly and had the ball in his glove, seemingly robbing Pham of the homer.

One problem: a little kid snatched the ball from Steer.

Also wearing a glove, the kid reached into Steer’s glove and pulled the ball out, leaving the left fielder slumped against the wall.

The umpires initially ruled Pham’s shot a homer and the hometown fans chanted “MVP! MVP!” at the kid when they saw video of his robbery.

The home run was negated after review, setting off a chorus of boos at Chase Field.

The Diamondbacks’ broadcast showed the kid and his family being removed from the game by security.
