STILLWATER, Okla. (AP) _ Richard Roby scored 27 points, including the decisive basket in overtime, as Colorado beat Oklahoma State 80-78 on Saturday afternoon, the Buffaloes' second Big 12 Conference road win of the season.

Colorado (13-3, 3-2 Big 12) hadn't won at Gallagher-Iba Arena since Jan. 12, 1980, a stretch of 20 games. The Buffs also hadn't won at Missouri since the 1996-97 season before they did so on Jan. 14.

Roby left the game Saturday with an injured ankle with 6:33 left in regulation, but the sophomore guard returned three minutes later and played most of the rest of the way.

With the score tied 78-78, Roby scored on a put-back with 45.3 seconds left, following a miss by Marcus Hall.

Oklahoma State (12-6, 2-2) had two chances to tie. First, Jamaal Brown missed a driving runner in the lane as the shot clock was winding down, and Mario Boggan missed a follow shot before Roby rebounded for Colorado.

Torre Johnson fouled Roby, who missed the front end of a one-and-one free-throw opportunity with 8.5 seconds left. Oklahoma State, out of timeouts, rushed the ball upcourt, but JamesOn Curry was held up briefly at midcourt by two defenders.

Curry broke free from the double-team and continued dribbling, but his pass to Terrel Harris sailed out of bounds as time expired.

Colorado led by as many as 11 points in the first half and was up 39-30 at halftime. The Buffs took control with a 14-3 run midway through the half, fueled by nine points by Roby.

Colorado led 45-34 with 18 minutes left but didn't score again for almost seven minutes. In the interim, the Cowboys scored 16 straight points to go ahead 50-45.

Roby scored on a driving runner with 33.7 seconds left in regulation to tie the game 71-71 and Oklahoma State then held the ball for the last shot. Curry missed a long 3-point attempt and Colorado's Marcus King-Stockton blocked a follow shot by Brown out of bounds with 2.2 seconds left.

After each team took a timeout, all the Cowboys could manage was an off-balance 10-footer by Johnson, which missed at the buzzer.

Colorado's 3-point shooting proved to be the difference _ the Buffs went 12 of 29 from behind the arc, compared to 5 of 15 for Oklahoma State.

It was the second straight down-to-the-wire finish at home for the Cowboys, who held off Texas A&M 79-77 on Jan. 11.

Roby's point total was his third-highest of the season, and he also had seven rebounds and six steals, all in the first half. Marcus Hall added 16 points for the Buffs.

Johnson scored 20 points and added 10 rebounds, while Boggan and Curry had 16 points each for Oklahoma State.
