Miguel Olivo charged the mound after being hit by a pitch from D.J. Carrasco in the fifth inning Sunday, touching off a benches-clearing brawl between the Chicago White Sox and Kansas City Royals.

Two innings later, Royals starter Zack Greinke was ejected with one out in the seventh when he hit Nick Swisher with a pitch after both dugouts had been warned. Royals manager Trey Hillman was also ejected.

Carrasco was just brought in from the bullpen to replace starter Clayton Richard. Carrasco threw a pitch high and tight to Olivo, who ducked out of the way, and the ball struck his bat for a foul. On the ensuing pitch, Carrasco hit Olivo and the Royals’ catcher charged the mound.

Olivo pulled up as if he was ready to punch Carrasco, a former Royals pitcher, when White Sox catcher A.J. Pierzynski grabbed him from behind. Olivo instead hit Pierzynski in the head, and by then both dugouts and bullpens had rushed the field.

Order was restored and Olivo, Carrasco and White Sox manager Ozzie Guillen were ejected.

Olivo began this season suspended for the first four games after throwing a punch at Jose Reyes of the New York Mets during the final weekend of last season while with the Florida Marlins, also igniting a benches-clearing brawl.
