The Wildcats (21-9, 10-8 Big 12), who had dropped four home games in conference play for the first time since 2005-06, took care of this one early. Behind a 51-percent shooting day, they took a 40-33 lead into halftime and stretched the advantage to 62-42 midway through the second half on a McGruder jumper.

Jordan Henriquez, two games removed from a career-high 19-point effort, added 16 points and eight rebounds off the bench for the Wildcats, who can secure a fifth-place finish in the Big 12 standings if Texas loses at No. 4 Kansas.

Oklahoma State (14-17, 7-11 Big 12), meanwhile, lost for the third time in four games and will carry a No. 7 seed into next week’s Big 12 Tournament, where it will take on Texas Tech in the opening round.
