For the second year in a row, UCLA leaves Boulder victorious.

The No. 25 Bruins earned their first win over a ranked team Thursday night, beating 21st-ranked Colorado, 69-56. Junior guard Norman Powell led the team with a 19 points, including 13 by halftime. The total tied his season high, and was accompanied by three rebounds and four steals.

Sophomore Jordan Adams had 14 points on an uninspiring 4-of-15 performance from the field, but grabbed a career-high 13 rebounds — six on offense.

That latter number helped UCLA continue its recent trend on the boards. Following strong efforts against No. 1 Arizona and Arizona State, it edged the Buffs with a 41-37 rebounding margin. The team survived an off-night from sophomore point guard Kyle Anderson, who didn’t score in the first half and finished with six points, five rebounds, six assists and three steals.

Without leading scorer Spencer Dinwiddie, Colorado never generated a strong push. UCLA is the only team the Buffs have has yet to beat since joining the conference for the 2011-12 season.

Askia Booker and Josh Scott scored 21 and 19 points, respectively, but no other player scored more than five points. The pair combined to shoot 14-of-23 from the field, including Booker’s 5-of-7 from beyond the arc. The rest of the team? Just 6-of-27.

UCLA led by 12 with less than five minutes remaining, but saw that margin shrink to seven after Booker’s fifth 3-pointer of the night. Colorado, however, squandered possessions and couldn’t put a late scare into the Bruins.
