BOULDER, Colo. (AP) - Dominique Collier celebrated Senior Day with a season-high 19 points and Colorado beat UCLA 80-76 Sunday for its first-ever season sweep of the Bruins.

Colorado (16-13, 8-9 Pac-12) took a nine-point lead into the locker room at halftime but came out cold in the second half, missed 14 of 18 shots and watched the Bruins (19-10, 10-7) roar back behind Aaron Holiday (21 points) and Kris Wilkes, who finished with 20 points.

UCLA went ahead 56-54 on Alex Olesinski's basket with 8:41 remaining, but the Bruins wouldn't score again until Wilkes' jam with just under four minutes left after the Buffaloes had surged to a 71-57 lead.

The Bruins had one last run left in them and cut Colorado's lead to 77-73 on Holiday's layup with 40 seconds left. Holiday sank a deep 3 to make it 80-76 with 15 seconds left.

George King added 16 points for Colorado and Lucas Siewert had 15.

Both teams sank 14 3-pointers, the Bruins in 31 attempts and the Buffs in 30. Namon Wright's 3 at the buzzer gave Colorado a 45-36 halftime lead.

BIG PICTURE

UCLA: The Bruins failed to join USC and Arizona in the 20-win club and were swept by Colorado for the first time since the Buffaloes joined the Pac-12 in 2011. The Bruins are heading in the wrong direction down the stretch. After winning six of their previous seven, they lost both games on this trip. They also lost at Utah 84-78 on Thursday night.

Colorado: The Buffaloes' only conference win on the road came against UCLA at Pauley Pavilion on Jan. 13, when they won 68-59. They're now 4-11 against the Bruins, but 3-3 at home. Colorado coach Tad Boyle improved to 3-7 against UCLA while Bruins coach Steve Alford fell to 5-3 versus Colorado.

UP NEXT

UCLA: The Bruins visit archrival USC next Saturday night before heading off to the Pac-12 tournament in Las Vegas. UCLA edged the Trojans 82-79 in a thriller on Feb. 2.

Colorado: The Buffs wrap up the regular season at Utah on Saturday. Colorado beat the Utes 67-55 in Boulder on Feb. 2.
