Brittany Chambers scored 26 points, and Kansas State rode its 3-point shooting to a 76-70 overtime upset of No. 12 Oklahoma State on Wednesday night.
Chambers made six of Kansas State's 16 3-pointers. Haley Texada added 14 points and Mariah White had 11 for the Wildcats (12-7, 3-4 Big 12), who made just seven shots from inside the arc and shot 35 percent overall.
Toni Young scored 22 points and Brittney Martin chipped in 15 for the Cowgirls (14-3, 3-3), who forced overtime on Tiffany Bias' jumper with 8 seconds left in regulation. But OSU never led in the extra session and saw its three-game winning streak snapped.
Oklahoma shot a respectable 46 percent from the floor, but the Cowgirls, who entered the game averaging a Big 12-leading 6.8 more turnovers per game than their opponents, committed an uncharacteristic 18 turnovers to the Wildcats' nine.
