Senior Night for Keiton Page, with the No. 4 Jayhawks in Gallagher-Iba Arena for the home finale of OSU's season.
The Cowboys lost at KU, 81-66, on Feb. 11.
The Jayhawks, 24-5 overall and 14-3 in the conference, pushed their lead in the Big 12 standings to two games with an 87-86 win over Missouri. KU could clinch its eighth straight league championship with a win in Stillwater.
OSU, however, beat No. 1 Kansas in Stillwater two years ago and has won two straight as underdogs against the Jayhawks in Gallagher-Iba.
“When I was in high school, my senior year,” said OSU redshirt freshman Brian Williams, “I saw when James Anderson and them were here and they beat Kansas and everybody rushed the floor.
“I got a little taste of that rush-the-floor against Missouri (this season). I want to do that again.”
With Saturday's win, the Cowboys moved to 7-9 in the Big 12. That's one win better than a year ago, when they finished 6-10.
OSU, picked for seventh in the preseason poll of coaches, also clinched at least the No. 7 spot.
