USC dropped its second Pac-12 Conference game of the season on Thursday night, losing 79-60 to Arizona State.
The Sun Devils were led by Jordan Bachynski's double-double, 20 points and 12 rebounds.
The Trojans were led by the 20-point effort of guard Byron Wesley who grabbed a career-high 14 rebounds.
"That was a tough game for us," USC coach Andy Enfield said after the game. "We played hard. Give ASU credit, they played well and beat us."
USC was tied at 13 with ASU nine minutes into the game before the Sun Devils began pulling away.
"We cam out for the first five or ten minutes and played hard," Wesley said after the game. "It wasn't our night. It's tough losing."
"Arizona State played a very good game," Enfield said. "We had some good runs, but they were able to respond."
Turnover trouble continues
USC committed 17 turnovers in their Sunday afternoon 107-73 loss at UCLA. The turnover trouble continued on Thursday in the loss to ASU.
"I'd rather have 11 or 12, I think that's a pretty good average number," Enfield said. "We had some issues tonight with some poor decisions, but even with 16 turnovers we should have had 20 assists. We made some good plays, but we missed shots."
The Trojans finished with 12 assists.
Thursday night shooting woes
USC shot a season low 36 percent from the field against the Sun Devils, making 22-for-61 shots.
They were 3-for-17 behind the three-point line.
"We're a streaking shooting team," Enfield said. "We need guys to be in rhythm and open. We took good shots and we missed good shots."
The Trojans only made 52% of their free throws Thursday night, finishing 13-for-25 from the line.
No. 1 Arizona next
USC (9-6, 0-2) will take on No. 1 Arizona (16-0, 2-0) on Sunday at 6pm PT in the Galen Center.
Enfield said after Thursday night's loss he's confident his team will stick together to prepare for the Wildcats. "We're staying positive with them," Enfield explained. "I love coaching them. It's frustrating when you play hard and don't win. We've got to stay together and compete, we need to do that Sunday against a very good Arizona team."
"The crazy thing is we've been practicing the best we have all year lately," Wesley said. "We're confident. We're looking forward to the Arizona game."
Sunday will be the first time USC will play a top-ranked team since facing No. 1 Stanford on Feb. 19, 2004.
