Los Angeles ? This time, Arron Afflalo got UCLA’s last shot. And with the game in his hands, he came through.

Afflalo hit a go-ahead 15-foot jumper with four seconds left, Darren Collison scored a career-high 17 points, and No. 4 UCLA rallied in the final 41â2 minutes to beat crosstown rival Southern California, 65-64, Saturday.

The Bruins (15-1, 4-1 Pac-10) were coming off a 68-66 loss at Oregon that knocked them out of the No. 1 ranking.

“The Oregon loss was real devastating and we didn’t want to experience that again,” Collison said.

In that game, UCLA went for a three-pointer to win, but Afflalo got trapped in the corner and the ball swung to Josh Shipp, who missed an off-balance attempt.

“I kind of expressed my frustration a little bit on how I at least want the ball in my hands for the last play, despite how I had been playing,” Afflalo said.

USC freshman Daniel Hackett’s pesky defense on Afflalo held UCLA’s leading scorer to two points in the first 20 minutes Saturday. But Afflalo opened the second half with consecutive three-pointers and then came up big at the end.

“You feel a little pressure after you make statements like that and the very next game you’re put in that situation,” said Afflalo, who finished with 15 points. “But once I got the ball in my hands, I don’t hear the crowd, I don’t hear anything. I’m looking to make that shot.”

The Trojans weren’t scared with the outcome in doubt, either.

Gabe Pruitt and Nick Young hit consecutive three-pointers to tie the score at 63 with 22 seconds to go. Young was fouled and made the free throw for a 64-63 lead.
