WASHINGTON — Washington Nationals outfielder Bryce Harper was suspended four games and San Francisco Giants reliever Hunter Strickland was suspended six games for their roles in Monday’s brawl at AT&T Park, Major League Baseball announced Tuesday.

Harper charged Strickland after being hit with the first pitch of the at-bat, throwing his helmet. Both players exchanged punches to the head before teammates joined the fracas.

No other players received suspensions for their actions.

MLB Chief Baseball Officer Joe Torre’s explanation of the disciplinary decisions said that Strickland had intentionally hit “Harper with a pitch, inciting the bench-clearing incident and fighting” while Harper’s suspension came “for charging the mound, throwing his helmet and fighting.”

The two players’ bad blood stems from a pair of home runs Harper hit off Strickland in the 2014 playoffs, when the Giants went on to capture their third World Series championship in five years.

Washington led 2-0 with two outs in the eighth inning and none on when Strickland drilled Harper on the first pitch — a 98 mph fastball. Harper immediately pointed his bat at Strickland, yelled at him and took off.

Harper flung his helmet and they began throwing punches, with the 6-foot-4 Strickland clocking Harper in the face. They then broke apart for a moment before squaring off again. Harper punched Strickland in the head as the benches and bullpens emptied.
