The Washington Nationals won Monday's game against the Detroit Tigers 5-4 on Clint Robinson's walk-off home run, but it was superstar Bryce Harper's actions during the ensuing celebration that turned heads.
Scott Linn of ESPN 980 and Yahoo Sports Radio shared a video that seemed to show Harper cursing at an umpire as the Nationals mobbed Robinson:

Bill Baer of NBC Sports noted that Harper "had apparently been chirping" at home plate umpire Brian Knight since he was called out on strikes in the bottom of the fourth inning.
