David Lee had 13 points and Stephen Curry, Draymond Green and Nemanja Nedovic each scored 12. Curry fouled out with 7:18 left in the third quarter on a three-point play by Chris Paul that tied the score at 68.
Trailing by eight, the Clippers narrowed the gap to 88-84 on two free throws by Spencer Hawes and a jumper by Griffin with 8:55 to play. But that was as close as they got.
Barnes responded with a 3-pointer from in front of the Clippers' bench and the Warriors closed it out with a 14-2 run during the final 5 1/2 minutes.
