Melvin Ejim had a double-double and Will Clyburn fueled a 12-0 second-half run, helping Iowa State survive an uncharacteristic 3-point drought to beat Oklahoma 73-66 on Thursday and end a seven-year losing streak in the Big 12 tournament.

The Cyclones, who led the country and set a school record with 309 3-pointers, missed 11 of their first 12 from behind the arc and fell 14 points behind. But they found the range in the second half and hit six 3-pointers while chalking up their first conference tournament win since 2005.

On Friday, the fifth-seeded Cyclones (22-10) will meet either top-seeded Kansas or No. 9 seed Texas Tech.

Ejim had 23 points and 12 rebounds, Clyburn had 17 points, and Georges Niang and Chris Babb each had 10.

Oklahoma (20-10) was led by Romero Osby's 18 points. Cameron Clark had 17.
