The benches cleared after Washington Nationals' Bryce Harper got into it with Giant's pitcher Hunter Strickland.
Harper got hit by a fast one and charged the mound during the Giants-Nationals game Monday.
The dugouts cleared and it got ugly.
The 6-foot-4 Strickland hit Harper in the face and then they broke apart for a moment before squaring off again.
Several of Strickland's teammates had to get him off the field.
Harper and Strickland were both ejected.
