STILLWATER, Okla. (AP) -- Andrea Riley scored 32 points, Tegan Cunningham added 20 and No. 20 Oklahoma State beat No. 13 Iowa State 78-70 on Wednesday night for its third straight win.

Riley, playing in her final home game, made a jumper from the right elbow and then set up Cunningham for a 3-pointer in the left corner as the Cowgirls (21-8, 9-6 Big 12) used a late 7-0 run to put the game away after Iowa State had eliminated a 10-point deficit.

Kelsey Bolte made six 3-pointers and scored 20 points to lead Iowa State (22-6, 10-5), which could have wrapped up the No. 2 seed in next week's Big 12 tournament with a victory.

The Cyclones played without starting point guard Alison Lacey, their top scorer and the nation's leader in assist-to-turnover ratio. She did not travel with the team because of an illness.
