Tyler Bey tallied his 12th double-double of the season, scoring 17 points and snagging 10 rebounds in Colorado's 71-63 win against Utah on Saturday.
Colorado (17-11, 8-8 Pac-12) took a nine-point halftime lead and stayed in front after intermission thanks to 15 points from Evan Battey and some cold shooting from both sides.
Utah (15-13, 9-7), which shoots a conference-best 39.6 percent from 3-point distance, was held to just five makes on 26 attempts (19 percent).
The Utes fell behind 8-0, failing to score until Timmy Allen's bucket at the 15:05 mark. Allen, who returned after a back injury sidelined him for two games, hit two more shots to spark a 9-0 run that gave the Utes a 9-8 lead when Sedrick Barefield capped the run with a 3-pointer. The Buffaloes took the lead for good on Tyler Bey's dunk with 9:25 left before halftime.
