O.J. Mayo added 12 points for the Trojans, who shot 68 percent from the field, 67 percent from 3-point range and 60 percent from the free throw line.

Roy Bright scored 22 points for Delaware State (3-6), which lost for the sixth time in seven games. The Hornets' losing margin was less than their 39-point defeat at Arizona State nearly two weeks ago. They will get one more chance against a Pac-10 team when they play at California on Thursday.

Bright was Delaware State's only player in double figures, bettering his 18.1-point average. The Hornets shot 38 percent from the field.

USC (7-3) played for the first time in nearly two weeks. The Trojans were coming off consecutive losses to No. 3 Kansas and No. 2 Memphis, both by four points, that dropped them out of the Top 25.

On the same day they returned to the rankings, the Trojans dominated the Hornets in every way.

USC raced to a 31-13 lead, its largest of the first half, while playing strong defense. The Hornets recovered slightly and outscored USC 11-8, with Bright getting five points, to end the half trailing 39-24.

The Trojans were even better in the final 20 minutes.

They outscored the Hornets 33-12 to open the half, including two 12-0 spurts. Jefferson dominated the early part of the run with eight points, then Angelo Johnson came in and made three 3-pointers before Mayo closed it out with a basket. Johnson finished with 11 points.
