BERKELEY, Calif. (AP) -- When Oregon erased California's eight-point halftime lead in the opening minutes of the second half Thursday night and built a lead of its own, the game looked like a repeat of the first meeting between the teams.
Then Ryan Anderson delivered the big plays Cal has lacked in recent weeks. Anderson's three-point play with 1:01 remaining helped the Golden Bears snap a six-game losing with a 63-61 victory over No. 15 Oregon.
"That's a gigantic win," Anderson said. "We need this kind of upset so we can go on our own streak. It was great to finally have the crowd run on the floor, and beat a ranked team. We've been playing ranked teams quite a bit this year and we finally knocked one off."
Cal (13-12, 5-8 Pac-10) held Oregon (20-6, 8-6) scoreless for the final 4:31 of the game -- including misses by Bryce Taylor and Chamberlain Oguchi in the final seconds -- to win for the first time since Jan. 18 at Oregon State and the first time in eight games this season against ranked opponents.
The Bears appeared unlikely to snap their skid after falling behind by 12 points midway through the first half. But Cal ended the half on a 17-0 run and then withstood a shooting spree by the Ducks early in the second to rally for the win.
Oregon made six of its first seven 3-pointers in the second half and 11 of its first 14 shots overall, building a 57-50 lead on Tajuan Porter's 3-pointer with 8:25 to play. That was reminiscent of the first meeting, when Oregon rallied from a 46-38 halftime deficit to win 92-84 at home in the game that started Cal's skid.
"We didn't want that to happen again," Anderson said. "We needed to stop Aaron Brooks. He's a second-half guy. He's their main scorer. He can take over the game. We focused on shutting him down."
In the final 8:26, Oregon scored only four points and none were by Brooks, the Pac-10's leading scorer.
Anderson scored on a tip-in that started a 7-0 run that tied the game before both teams struggled to score down the stretch.
Taylor put Oregon up 61-59 with 4:31 to go on a putback, but the Ducks didn't score again, including a pair of missed free throws by Malik Hairston with 1:41 remaining.
Anderson's three-point play off a nice pass from Ayinde Ubaka gave Cal the lead.
"I take it upon myself to make a play," Ubaka said. "I want the ball in my hands down the stretch."
After Brooks missed a runner with 37 seconds remaining, Ubaka made one free throw on the other end. Taylor then missed a potential tying shot with 17 seconds to go, but Oregon got another shot after Alex Pribble missed the front end of a one-and-one.
Taylor missed a shot from the corner and Chamberlain couldn't convert the offensive rebound, sending the Cal students onto the floor in celebration.
"They made plays down the stretch," Oregon coach Ernie Kent said. "We had plays to make and we didn't make them like we did earlier in the year."
Porter scored 14 points to lead the Ducks, who have lost five of seven. Brooks added 12 points and Taylor had 11.
Brooks' jumper on Oregon's first possession of the second half ended a more than seven-minute scoreless stretch for the Ducks. Brooks had shot just 4-for-28 in his previous five halves, scoring just 13 points in the stretch. But he made his first four shots of the second half, including a pair of 3-pointers, before missing his final three shots.
"We just stepped up our defensive pressure and they started missing shots," Ubaka said. "They're a great shooting team and they just missed shots they usually make."
Cal was down 12 early and it would have been more if not for Christopher. He made five of his first seven shots, while the rest of the team was just 1-for-12 in the opening 14 minutes as the Bears fell behind 27-18.
Christopher got help from his teammates just as the Ducks fell into a slump. Anderson started a 17-0 run to close the half with a 3-pointer and had eight points in the spurt that was aided by Oregon's offensive struggles.
The Ducks didn't score for the final 6:08 of the half and Joevan Catron's layup was their only basket in the final 9:23. On their final 10 possessions, the Ducks committed three turnovers, missed seven 3-pointers and didn't shoot a single shot from inside the arc.
"I don't even think you can explain it," Hairston said. "That's bad basketball."
