The San Diego Padres and Los Angeles Dodgers benches cleared during the eighth inning of their game on Friday after Padres coach Mark McGwire and Dodgers coach Derek Shelton exchanged words. McGwire shoved Shelton, who retaliated with a punch. Both coaches were ejected, and the incident led to a benches-clearing brawl. The altercation came after Manny Machado of the Padres was hit by a pitch from Blake Treinen of the Dodgers.
