The second-ranked Kansas Jayhawks seized control of the game with a 30-9 run into halftime, then used a 32-11 run to finish the game for a 94-67 victory over an Oklahoma State Cowboys team that beat them by 19 just last month.

Wayne Selden Jr. led the Jayhawks (22-4, 10-3 Big 12) with 18 points. Landen Lucas had 14 points and 10 rebounds, Perry Ellis shrugged off a slow start to score 15, and Frank Mason III finished with 14 points.

Oklahoma State (12-14, 3-10) led much of the first half, fell behind by 18 early in the second, then trimmed their deficit to 62-56 with about 11 minutes to go. But that's when the Jayhawks caught fire down the stretch, pulling away for a lopsided victory over Self's alma mater.

Jeff Newberry scored 19 points and Jeffrey Carroll had 13 for the Cowboys, who again played without leading scorer Jawun Evans. The freshman has been sidelined since hurting his right shoulder Feb. 3.

The Jayhawks' lead swelled to 18 points early in the second before Oklahoma State went on a run of its own, trimming its deficit to 61-54 at the under-12 timeout. But the Jayhawks answered with a coldly efficient 10-0 to regain control, and they waltzed the rest of the way to their sixth straight win.
