LARAMIE, Wyo. (AP) - Leonard Washington scored 22 points and Larry Nance Jr. added 14 as Wyoming used a stingy defense to beat No. 19 Colorado 76-69 Saturday night.
Luke Martinez added 13 points, while Josh Adams and Derrious Gilmore each scored 12 as Wyoming (8-0) beat a ranked opponent at home for the eighth time in 13 games since the 1995-96 season.
Spencer Dinwiddie scored 24 points and Andre Roberson had 16 points and 12 rebounds for Colorado (6-1), which was off to its best start since 1989-90.
However, the Cowboys' aggressive, swarming defense held the Buffaloes below their 76-point scoring average.
Askia Booker, Colorado's leading scorer at 16.8 points a game coming in, finished with six points. Josh Scott, who was averaging 14.5, had five.
Wyoming held Colorado to 41.4 percent shooting (24 for 58) from the floor, while the Cowboys hit 48 percent (24 for 50).
Both teams had trouble scoring in the first half, with Colorado leading 28-26 at halftime as Roberson and Dinwiddie scored seven points each. Washington kept Wyoming close with 11 points and two blocked shots.
But the Cowboys began the second half with a 12-6 run to go up 38-34 on Nance's 3-pointer with 15:10 remaining.
Wyoming didn't trail again as it continually answered any charge by the Buffaloes and eventually built a 12-point lead _ the largest of the game _ when Washington converted a three-point-play with 2:26 remaining to put the Cowboys ahead 64-52.
Colorado lost three starters, including Roberson, to fouls in the final minutes, while Wyoming hit enough free throws to hold the Buffaloes off.
The Cowboys made 21 of 33 free throws, while Colorado was 12 of 15.
Adams, who entered the game averaging 3.8 points, shot 3 for 6 on 3s.
