Jerryd Bayless scored 33 points and Arizona beat California 83-73 Thursday night, the Wildcats' 13th straight homecourt victory over the Bears since 1995.
Freshman Bayless scored 18 of his points in the first half and hit several clutch 3-pointers in the second as Arizona ended a two-game losing streak. He finished 5-of-9 from behind the three-point arc.
The Wildcats (16-8, 6-5 Pac-10) also got scoring help from Jordan Hill, who had 21 points and 11 rebounds. Chase Budinger added 18 points, 15 coming in the second half.
Patrick Christopher led California (14-9, 5-7) with 21 points. Ryan Anderson added 19 and Jerome Randle pitched in 17 for the Bears. DeVon Hardin had 11 points in the contest, but only one after halftime.
Unlike Sunday's game when Bayless scored 39 points in a 59-54 loss to Arizona State, he received help from his teammates against Cal, with Hill taking control of the lane in the game's final stages.
Bayless hit a 3-pointer to put Arizona up 55-49 lead with 8:42 remaining and then another shortly after to make it a 62-54 lead.
Hill scored six quick points, including a thunderous dunk, for a nine-point lead with 5:48 remaining.
Cal, down 31-30 at halftime and behind by 11 points early in the second half, tied the score at 41 on Christopher's dunk with 14:15 remaining.
The Wildcats then scored seven unanswered points and took control from there.
