Little Girl Fires Daddy's Foul Ball Back!!!

He made the catch of the game -- pulling in a foul ball at yesterday's Philadelphia Phillies game from his seat in the stands -- but when Steve Monforto handed the precious ball to his little daughter Emily ... she threw the ball back onto the field!

Monforto was all class after the blunder -- immediately turning to comfort his daughter ... because he "wanted to let her know that ... she didn't do anything wrong." Dude also told that a Phillies rep brought him a replacement ball as a souvenier later in the game.

As for Emily -- girl's got one hell of an arm!
