The Wildcats hit seven consecutive shots in the last three minutes of the final period to blow the game wide open. Arizona’s second-half scoring kick was too much for the Trojans to handle, as USC (21-7, 8-7) dropped its third consecutive conference game in a 90-77 loss at the McKale Center on Thursday night. “We got better this week. We played hard tonight,” head coach Andy Enfield said to the media. “We played well enough offensively we just could not stop them down in the second half.”A 3-point field goal from sophomore forward Bennie Boatwright pulled the Trojans within a 51-49 deficit of the Wildcats with over 15 minutes remaining in the game.Arizona (26-3, 15-1) responded with a 20-6 scoring run over the next five minutes of play.

A 3-point shot from junior Arizona guard Parker Jackson-Cartwright gave the Wildcats their largest lead of the night at 78-62 with just over five minutes to play. “They got rolling on offense,” Enfield said. “It’s hard to guard Arizona when they’re shooting the ball at that level. I give Arizona credit. They really played well on offense [and] shot the ball well.”As a team, Arizona finished Thursday night shooting 11-for-20 (55 percent) from beyond the arc. Overall, the Wildcats shot 32-for-63 (51 percent) from the field against the Trojans.

The Wildcats were able to convert on four 3-point field goals in the final 2:30 of the first half. “Arizona did a great job of closing out in the first half,” Enfield said. “They played some great defense against us, too.”The Trojans attempted to mount a comeback late in regulation, pulling within an 80-73 deficit on a pair of Boatwright field goals with under two minutes left in the game. USC had a 20-6 run of its own early on in the first half. With six minutes remaining before the half, the Trojans held a 28-19 lead over Arizona.

Boatwright and Metu were two of USC’s four double-digit scorers on Thursday. Junior guard Elijah Stewart and freshman guard De’Anthony Melton finished with 13 and 10 points scored, respectively. Melton also recorded a team-high four assists against the Wildcats. After completing a dunk with 13:21 minutes left in the second half, Metu landed awkwardly and appeared to suffer a minor ankle injury that forced him to leave the game. After taking a quick trip to the locker room, Metu made a prompt return to the floor to play. He scored nine points after returning to the game with 12 minutes left in play. USC will remain in the desert for its final road game of the season against Arizona State (13-15, 6-9) on Sunday. The Trojans will look to avoid their fourth consecutive loss in conference play.
