Bryce Harper was at bat for the Nationals yesterday in a game against the Reds and a heckler in the stands yelled out "Overrated!" just as he stepped to the plate. Harper proceeded to hit the next pitch about a mile to dead center field for his SECOND home run of the game. If you listen closely at the beginning of the video clip below, you'll hear the fan yell.
It's not really surprising that the heckler was audible, considering it looks like there were about 100 fans in attendance at the game!
