Naadir Tharpe hit a floater with 18 seconds left in double-overtime to give Kansas a one-point lead, and Oklahoma State guard Markel Brown missed a 19-footer with 10 seconds left before Travis Releford tipped the ball forward to run out the time in KU's 68-67 double-overtime victory over OSU on Wednesday night at Gallagher-Iba Arena in Stillwater, Okla.
Tharpe's jumper was KU's only field goal made in the two overtimes.
Travis Releford led KU with 18 points on 7-for-10 shooting, while Jeff Withey added 17 points, 14 rebounds and four blocks.
KU (22-4, 10-3 Big 12) moves into a tie for first place in the Big 12 with Kansas State.
The Jayhawks will play host to the TCU Horned Frogs at 3 p.m. Saturday.
