AMES, Iowa (AP) -- Andy Osborn hit a 3-pointer with 15.9 seconds left in overtime to give Colorado the lead and the Buffaloes held on through a frantic finish to beat Iowa State 54-52 Saturday night for their first Big 12 victory.
Colorado (9-7, 1-4 Big 12) pulled it out despite going scoreless the final 4:46 of regulation, committing 20 turnovers and shooting just 33 percent. The Buffaloes offset those sordid numbers with a 54-35 rebounding advantage, including 22 offensive rebounds that led to a 21-11 edge in second-chance points.
Iowa State (8-7, 0-4) failed on chances to win it both at the end of regulation and overtime and lost for the fifth straight time. It was the Cyclones' 10th straight overtime loss in conference play since a victory over Nebraska in 1995.
Glean Eddy led Colorado with 12 points and 11 rebounds, while Chris Copeland scored 10 for the Buffaloes, who ended a 13-game losing streak at Iowa State. Curtis Stinson led Iowa State with 15 points and Will Blalock scored 14.
Iowa State led 52-50 after Stinson made one of two free throws with 24.2 seconds remaining. Osborn, distinctive in his headband, goatee and knee-length black socks, then got free to the right of key and swished the 3-pointer to put the Buffs up 53-52.
Osborn got the rebound after Iowa State's Damion Staple missed inside and was fouled. He made the first free throw with 8.4 seconds remaining, missed the second and Eddy got the rebound. But he was called for traveling, giving the ball to Iowa State with 5.5 seconds to play.
Both teams then swatted the ball around after Iowa State inbounded and the buzzer sounded as it rolled out of bounds. The officials checked the TV monitor and put one-tenth of a second back on the clock, giving Iowa State one last chance.
Blalock lobbed to Jared Homan, who could only bat at the ball. It fell well short and Colorado had the victory. Iowa State fans booed and some threw towels and other debris onto the floor as the Colorado players jogged to their locker room.
Iowa State scored the final five points of regulation after Colorado took a 42-37 lead on Marcus Hall's layup with 4:46 to play. The Cyclones tied it on Homan's free throw at the 1:14 mark, then missed three shots in the final 8 seconds.
