Jesse Perry scored a game-high 20 points and visiting Arizona kept Southern Cal winless in Pac-12 play with a 57-46 victory.

Arizona (11-5, 2-1, Pac-12) never trailed and led Southern Cal (5-12, 0-4 Pac-12) by 16 points at halftime. The Trojans are the only Pac-12 team without a league win.

Solomon Hill notched his fourth double-double with 11 points and 10 rebounds, and Nick Johnson grabbed seven rebounds for Arizona, which earned a rare victory in Los Angeles. The Wildcats entered the game 2-11 in regular-season games in Los Angeles since 2006.

Southern Cal, which came in averaging a conference-worst 54.4 points, shot 20.7 percent (6 of 29) in the first half and finished at 29.3 percent. The Trojans have lost five straight and eight of their last nine games.

After USC missing its first 11 3-pointers, Maurice Jones made the Trojans’ first with 10:50 to play. Jones scored a team-high 14 points on 3-of-13 shooting, and Dewayne Dedmon had 11 points and eight rebounds after battling early foul trouble.

Southern Cal finished 1 of 15 (6.7 percent) from beyond the arc, while the Wildcats were just 2 of 15 (13.3 percent).
