STILLWATER, Okla. (AP) -- Le'Bryan Nash scored 18 points to help Oklahoma State upset No. 8 Kansas 67-62 on Saturday.
Oklahoma State trailed by 11 at halftime, but the Cowboys held the Jayhawks to 27 percent shooting in the second half. Oklahoma State students stormed the court after beating the Jayhawks at home for the second straight year.
Anthony Hickey added 15 points for the Cowboys (16-7, 6-5 Big 12), who were coming off a win over No. 25 Texas on Wednesday. Phil Forte, Oklahoma State's leading scorer for the season, had flu-like symptoms and was limited to 29 minutes. He finished with 13 points.
Oklahoma State beat a ranked opponent at home for the third time this season and improved to 11-2 at Gallagher-Iba Arena.
Wayne Selden, Jr. scored 15 points, and Perry Ellis, Frank Mason II and Brannen Greene each added 10 points for the Jayhawks (19-4, 8-2), who had won five straight.
Oklahoma State overcame an 11-point halftime deficit, and Nash's spinning left-handed layup put the Cowboys up 59-52 with 7:21 to play.

Mitchell Solomon's baseline jam on a nice find by Newberry cut Kansas' lead to 30-24, forced a timeout and brought the crowd back into the game.
