LAWRENCE, Ks. - The Big 12 continues to go in favor of Kansas.
Senior center Jeff Withey posted 13 points, nine rebounds and four blocks, while freshman guard Ben McLemore added a game-high 18 points as the Jayhawks smothered Oklahoma, 67-54, Saturday in Allen Fieldhouse.
The victory was the 17th in a row for Kansas, the longest streak in the country, while pushing the No. 3 Jayhawks to 18-1 overall and 6-0 atop the Big 12.
The loss was the 12th straight for the Sooners at Kansas, dating to 1993.
Withey, who ranks third nationally in blocks, was held without a rejection in the Jayhawks' previous game, a win at Kansas State. The 7-footer asserted himself early, however, against Oklahoma and was a force inside throughout the game.
Forwards Romero Osby and Amath M'Baye led the Sooners (13-5, 4-2 Big 12) with 12 points apiece, but combined to go just 8 of 27 from the floor. Oklahoma shot just 35.6 percent while tumbling from second place in the Big 12.
Back-to-back 3-pointers by the Jayhawks' Naadir Tharpe and McLemore bumped the Jayhawks' lead to 49-35 with 8:44 left after the Sooners had narrowed the gap to eight. Oklahoma never pulled within single digits again.
Withey led the Jayhawks with nine first-half points and also asserted himself inside with seven rebounds and four blocks. His last rejection led to a breakaway dunk by Travis Releford to give Kansas an 11-point lead, its biggest of the half.
The Sooners got eight points from Pledger, but shot just 8 of 28 for the half. They went five-plus minutes without a field goal during one stretch. The 29-21 deficit for OU represented the fewest points it has scored in a half this season.
