The Trojans struggled all night on offense and had an abysmal first half, scoring just 23 points to fall behind by 12. In the second half, USC picked up the production and outscored San Diego State 37-31, but the comeback effort was too little too late.
Four of the Aztecs starters reached double figures with guards Jamaal Franklin and James Rahon each scoring 17 points. Eric Wise led the Trojans with 14 points and seven rebounds, but was the only USC player to score double digits. The bench was a bright spot for the Trojans with their second unit outscoring San Diego State 20-4.
Both teams had success shooting 3-pointers with the Aztecs making an efficient 17-of-22, while USC converted 11-of-20. The Trojans, however, had trouble shooting from everywhere else on the floor, making just 24 percent from inside the arc and hitting only 5-of-17 at the free throw line.
USC will now have a week of rest before returning to take on the Nebraska Cornhuskers on the road on Dec. 3.
