KANSAS CITY, Mo. — Keiton Page scored 19 of his 24 points in a dominating first half, and Oklahoma State withstood a brief rally in the season's third Bedlam game to beat Oklahoma 81-67 on Wednesday night in the opening round of the Big 12 Tournament.
Oklahoma State (22-9) raced to an 18-point lead in the first six minutes, then allowed Oklahoma to creep back in it with a shaky start to the second half. Obi Muonelo kept the Sooners from completing the comeback, scoring 10 of his 15 points after the rally to send the seventh-seeded Cowboys into Thursday's quarterfinals against ninth-ranked Kansas State, the No. 2 seed.
Oklahoma (13-18), seeded 10th, played without leading scorer Willie Warren (ankle) and will miss the postseason a year after reaching the NCAA regional finals.
The Sooners closed out a disappointing year filled with injuries, suspensions and inconsistency with a nine-game losing streak, their longest since dropping 10 in a row in 1963-64. Tommy Mason-Griffin had 22 points and nine assists, and Steven Pledger added 18 points for Oklahoma.
The third Bedlam game came after a split in the regular season.
Oklahoma won in overtime at home with the Big 12 player of the year, OSU's James Anderson, on the bench for most of the second half with a head injury. With Anderson back, the Cowboys won by 21 in the second meeting in Stillwater.
