TUCSON, Ariz. —
Nick Johnson scored 18 points, Brandon Ashley added 15 and top-ranked Arizona remained unbeaten with a 69-57 win over Colorado on Thursday night.
Arizona (19-0, 6-0 Pac-12) had a week off after blowing out rival Arizona State and raced out to an early 14-point lead.
Aaron Gordon added 12 points for Arizona, which overcame a 3-for-15 night from 3-point range and some missed free throws down the stretch to extend the best start in school history.
A year after nearly pulling off an upset in the desert, Colorado (15-5, 4-3) had no chance for late-game heroics in its third game without injured leading scorer Spencer Dinwiddie.
The Buffaloes struggled to slow Arizona's bevy of scorers and couldn't overcome the big early hole, falling to 0-16 against No. 1 teams. Xavier Johnson led Colorado with 21 points and Josh Scott added 15.
