Andre Roberson, Askia Booker and Carlon Brown scored 13 points apiece and Colorado won its first Pacific-12 Conference road game with a convincing 74-50 victory over injury-depleted Southern California Thursday.

Colorado (14-6, 6-2 Pac-12) opened the second half on an 18-2 run and was never tested by Southern Cal (5-16, 0-8 Pac-12), which lost its ninth straight game.

The Trojans played the second half with six scholarship players after forward Dewayne Dedmon left with a knee sprain. Southern Cal is the only Pac-12 team without a conference win.

After going scoreless on 0-of-8 shooting against Arizona last Saturday, Roberson was 5-of-11 shooting with 10 rebounds against Southern Cal. Colorado outrebounded the Trojans 49-23.

Austin Dufault added 11 points for Colorado, which has struggled on the road after going 11-1 at home. The Buffaloes lost their first two conference road games against California and Stanford last week.

Maurice Jones scored 13 points and Byron Wesley added 12 for Southern Cal, which shot 19-of-59 (32.2 percent) from the field and 5-of-25 (20 percent) from beyond the arc.
