Washington Nationals outfielder Bryce Harper could face punishment from Major League Baseball for his outburst directed at an umpire during the ninth inning of Monday night's game against the Detroit Tigers.
The league office is reviewing Harper's actions near the end of the Nationals' 5-4 victory over the Tigers at Nationals Park when Harper was ejected while in the dugout by home plate umpire Brian Knight after teammate Danny Espinosa was called out on strikes.
