In the fourth inning Thursday night, Nationals OF Bryce Harper hit a solo home run.
He then shushed the crowd behind the on-deck circle as he walked to the dugout heading home.
In 300 plate appearances during his career against the Mets, Harper is batting .265 with 16 HR and 40 RBIs.
Wild guess here, but I assume Mets fans in that area were likely taunting Bryce while he was warming up for the at-bat. And, if I had to bet, this isn't the first time... and it shouldn't be the last. So, strutting back to the dugout, he flips them a little payback.
