Kerr, irate and swearing after a pair of loose-ball fouls on Kevon Looney 18 seconds apart, was ejected with 3:34 left in the third after he went onto the court to argue.
After four straight Kings free throws -- one for a technical on Draymond Green before Kerr erupted -- Stephen Curry and Klay Thompson hit consecutive 3-pointers as the Warriors went ahead 79-78.
"I was mad about a lot of things, but I got what I deserved," Kerr said after the game. "I deserved to be ejected, so I was, so I have no complaints."
Kerr and his former top assistant, now Lakers coach Luke Walton, are the only coaches to be ejected at first-year Golden 1 Center. Walton was tossed Dec. 12 for going to nearly the same place on the court.
