California ended a 19-game losing streak to UCLA when Michael Davis forced a fumble on the Bruins' final drive yesterday, enabling the Bears to hold on for a 38-31 victory in Berkeley.

Two California running backs rushed for over 100 yards as the Bears jumped to a 17-0 lead and never trailed, although they nearly blew a 21-point, fourth-quarter lead. Anthony Wallace finished with 134 yards, while Russell White gained 125. Each player scored a touchdown.

Cal (5-2, 3-1 in the Pacific-10), which last beat UCLA in 1971, defeated the Bruins at home for the first time since 1968.

UCLA (3-4, 2-2) trailed, 38-17, with 10:42 remaining before starting its comeback on Kevin Smith's one-yard touchdown plunge. On its next possession, UCLA's Scott Miller recovered a fumble in the end zone following a 26-yard pass completion from Maddox to Reggie Moore, cutting the lead to 38-31.

After Wallace fumbled on his own 37 with 4:58 to play, UCLA drove to Cal's 14 before quarterback Tommy Maddox was blindsided by safety Michael Davis and fumbled. Joel Dickson recovered and the Bears ran out the final 3:43 to give them their first four-game winning streak since 1978.

Arizona 35, USC 26: In Los Angeles, quarterback Ronald Veal came off the bench to score three second-half touchdowns, rallying the Wildcats (5-2, 3-2) to their first victory in seven meetings over the 15th-ranked Trojans (5-2, 2-2) in a Pac-10 game.

Arizona took a 28-17 lead early in the fourth quarter. With the ball on the Trojans 31, left guard Richard Warren picked up Veal's fake fumble and ran 28 yards to set up the score. Veal, who replaced starting quarterback George Malauulu at halftime, scored one play later.

Southern Cal, which lost for the first time in three games, got a 25-yard field goal by Quin Rodriguez with 8:58 left. But Veal scored again with 7:31 remaining.

Wyoming 21, Weber St. 12: Tom Corontzos threw for two touchdowns and Dwight Driver rushed for 105 yards and a touchdown as the No. 21 Cowboys held off the Division I-AA Wildcats in Laramie, Wyo.

Driver, Wyoming's first 100-yard rusher this season, scored from six yards early in the second quarter after Weber State had taken a 3-0 lead on Brent Chuhaniuk's field goal. Wyoming (8-0) led by 7-6 at the half after being unable to sustain its drives against Weber State (4-4). The Wildcats squandered several scoring opportunities in the second half.

Washington 52, Stanford 16: In Stanford, Calif., quarterback Mark Brunell accounted for three touchdowns and Greg Lewis ran for two more as the 13th-ranked Huskies (6-1, 4-0 Pac-10) crushed the Cardinal (2-5, 1-3).

Wash. St. 55, Oregon St. 24: In Corvallis, Ore., freshman quarterback Drew Bledsoe passed for 188 yards and three touchdowns in his first collegiate start and the Cougars (3-5, 2-2 Pac-10) scored on six straight possessions to beat the Beavers (1-6, 1-2).

Oregon 27, Arizona St. 7: Brian Brown returned a punt 86 yards for the go-ahead touchdown and Steve Kemp returned an interception 81 yards for a score as the Ducks (5-2, 1-2 Pac-10) rolled over the visiting Sun Devils (2-4, 0-3).
