California Upsets No. 4 UCLA LOS ANGELES (AP) -- Tremaine Fowlkes scored a career-high 24 points and California kept up its mastery of UCLA on the fourth-ranked Bruins' home court with a 100-93 victory Saturday. Cal (11-5, 3-4 Pac-10), the only team to beat UCLA at home last season, won its third straight at Pauley Pavilion. UCLA (12-2, 6-2) had its six-game winning sreak snapped and fell into a tie with Arizona for the Pac-10 lead. Fowlkes, a 6-foot-6 freshman out of Crenshaw High School in Los Angeles, singlehandedly lifted the Golden Bears out of a tight game with 9 straight points midway through the second half. UCLA played catch-up most of the first half and never led in the second. The Bruins got within 1 on a basket by George Zidek with 15:31 left and tied the game three times after that. Fowlkes broke the last tie with a 3-pointer that started a 14-3 run, including 12 points of his own, and put Cal ahead 77-66 with 7:14 to play. Fowlkes' spurt came with both Ed O'Bannon and Charles O'Bannon on the bench for UCLA. Ed, whose 16 points in the first half kept the Bruins in the game, picked up his fourth foul with 11:45 left. He fouled out with 20 seconds remaining. Cal held the Bruins scoreless for a 1:07 span in the final minutes using a zone defense that stymied UCLA thoughout the game. Jelani Gardner, who was heavily recruited by UCLA, added 18 points for Cal. Ed O'Bannon led UCLA with 23 points and Tyus Edney added 21 points and five steals. The steals broke UCLA's career record of 189 set by Pooh Richardson from 1986-89. The Bruins escaped with a 3-point win over No. 17 Stanford on Thursday, despite poor free-throw shooting and foul trouble. They never got in the game against a resurgent Cal team, whose 7-0 start was its best in 27 years. Cal then lost 5 of 6 and injuries also took a toll on one of the Pac-10's youngest lineups. Forward Alfred Grigsby (hamstring) and K.J. Roberts (shoulder) saw their first significant action Saturday after missing several games. Cal led 52-45 at halftime after going up by 14 points midway through the half. The Bruins got as close as 20-16 before the Bears used an 18-10 spurt, including 8 by Fowlkes, to lead 38-26.
