John Lee kicked five field goals, four of them from more than 40 yards, and Dennis Price returned an interception 63 yards for a touchdown yesterday to give UCLA a 29-10 upset over seventh-ranked Southern California in a Pacific-10 game before 90,096 yesterday in Pasadena.

Lee's performance gave him an NCAA-record 29 field goals this season. He broke the record of 28, set by West Virginia's Paul Woodside in 1982 and equaled by Arizona State's Luis Zendejas last year. Lee's only misses this season were from 41, 44, 49 and 50 yards.

The Bruins (8-3 overall and 5-2 in the conference) assured themselves of a berth in a bowl game. They hadn't beaten USC three straight times since 1953-55.

USC (8-2 and 7-1), which clinched the Pac-10 title and a berth in the Rose Bowl game Jan. 1 last week by beating then top-ranked Washington, committed five turnovers that led to 16 UCLA points.

The Trojans played most of the game without starting tailback Fred Crutcher, who incurred a strained groin muscle. Before leaving the game for good early in the second quarter, he gained 34 yards on 11 carries, giving him a season total of 1,009 yards. His replacement, freshman Ryan Knight, gained 100 yards on 25 carries. UCLA's leading rusher was also a freshman, Gaston Green; he gained 134 yards on 18 carries.
