SAN DIEGO — Zack Greinke had his left arm in a sling and a dazed look on his face as he told his side of the story. Barely two hours before, the $147 million Dodgers pitcher was injured in a wild fight with the San Diego Padres that didn’t even end when the game did.

Greinke broke his left collarbone in a bench-clearing brawl during Los Angeles’ 3-2 victory Thursday night, leaving the Dodgers so furious that Matt Kemp confronted Padres slugger Carlos Quentin nose-to-nose as the two were leaving Petco Park.

Juan Uribe’s pinch-hit home run in the eighth put the Dodgers ahead, two innings after Greinke hit Quentin on the left shoulder with a pitch.

The slugger started walking toward the mound and Greinke appeared to say something. The 6-foot-2, 240-pound Quentin then charged the 2009 AL Cy Young Award winner, who is 6-2 and 195 pounds. They dropped their shoulders and collided, and Quentin tackled the pitcher to the grass.

Quentin and Greinke ended up at the bottom of a huge scrum as players from both sides ran onto the field and jumped in.

Dodgers manager Don Mattingly was livid, saying it shouldn’t have happened because Quentin was hit on a 3-2 pitch in a one-run game.

“That’s just stupid is what it is,” Mattingly said. “He should not play a game until Greinke can pitch. If he plays before Greinke pitches, something’s wrong. He caused the whole thing. Nothing happens if he goes to first base.”

Greinke twice hit Quentin with pitches when they were in the AL.

Quentin said his history with Greinke has been “well-documented. That situation could have been avoided. You’d have to ask Zack about that.”

“I’ve been hit by many pitches,” said Quentin, plunked more often than any other major league hitter since the start of 2008. “Some have been intentional, some have not been. For the amount I have been hit and my hitting style, I’m going to repeat: I have never reacted that way.”

Both teams said the melee could have been avoided.
