Xavier Johnson scored 20 points and Colorado completed a season sweep of Southern California with an 83-74 victory Sunday, sending USC to its sixth straight loss.
Five players scored in double figures for the Buffaloes (19-7, 8-5 Pac-12). This is the school's best start after 26 games since the 1996-97 squad opened 19-7 and ended up in the NCAA tournament. But the Buffaloes are 5-4 since leading scorer Spencer Dinwiddie's season ended because of a torn ACL that occurred on Jan. 12 at Washington.
Johnson, Askia Booker (18 points), Josh Scott (17 points), Xavier Talton, and reserve Jaron Hopkins accounted for all but four of Colorado's points, including a season-high eight 3-pointers.
Byron Wesley scored 21 points for the Trojans (10-15, 1-11), who are last in the conference under first-year coach Andy Enfield. Their only victory against a Pac-12 opponent was Jan. 22, when they beat California 77-68 at home.
