LOS ANGELES (AP) – Ayinde Ubaka scored eight of his career-high 29 points in overtime and California stunned fourth-ranked UCLA 76-69 in the Pac-10 tournament quarterfinals Thursday night. UCLA’s second straight loss dealt a serious blow to its hopes of being a No. 1 seed in next week’s NCAA tournament. The five-minute overtime turned into a blowout, with Cal outscoring the Bruins 15-8. The game was a rematch of last year’s Pac-10 title game, won by UCLA on its way to a runner-up finish in the national championship game. Ryan Anderson added 18 points for the eighth-seeded Golden Bears (16-16), who blew a 16-point first-half lead. They will play Oregon in the semifinals; the teams split their two games during the season. Darren Collison had 20 points, Josh Shipp 19 and Luc Richard Mbah a Moute 13 for the top-seeded Bruins (26-5), who lost their regular-season finale at Washington. UCLA’s Arron Afflalo, the Pac-10’s player of the year, had his worst offensive performance of the season with three points, ending a streak of 29 games in double figures. Ubaka tied the game at 59 on a 3-pointer after a wild scramble with 54 seconds left in regulation. Collison drove the lane and scored to put the Bruins in front until Ubaka’s floater with 15 seconds left forced overtime. Collison couldn’t answer again when his 3-pointer missed in the closing seconds. Afflalo scored his only field goal of the game to open overtime, but he never connected again. The Bruins watched as shots hit the rim and the Bears’ offensive momentum continued unabated. Omar Wilkes, the son of former UCLA star Jamaal Wilkes, scored on a one-handed scoop to tie the game at 63. Ubaka hit a jumper that gave Cal the lead for good. Eric Vierneisel made four consecutive free throws as the Bears pulled away. Down by 12, the Bruins opened the second half with a scoring burst nearly identical to the one Cal generated in the first 20 minutes. Their 20-4 run helped them take the lead, 45-41, for the first time since the game’s opening moments. Collison had nine points, including a steal and fastbreak dunk, and Mbah a Moute added six. The Bears struggled on 1-of-8 field-goal shooting against UCLA’s increased defensive pressure. Mostly though, the Bruins went to the line as Cal was called for 10 fouls in 8 1/2 minutes after having six in the first half. The Bruins were only 7-of-17 from the line in that stretch. Neither team led by more than four points over the final 8 1/2 minutes of regulation. Ubaka’s 3-pointer went in as the shot clock expired, putting Cal ahead 56-53. The Bruins scored six straight points for a 59-56 lead before Ubaka’s two straight baskets ensured overtime. The Bears outscored UCLA 23-5 in the first half for a 16-point lead. Afflalo had zero points and three fouls, while Collison was scoreless with five of UCLA’s 11 turnovers. 160Want local news?Sign up for the Localist and stay informed Something went wrong.
