Georges Niang shot 9-of-25 from the field and 2-of-9 beyond the arc before fouling out in the extra period, but had 22 points for Iowa State (23-7, 11-7 Big 12), which secured at least a No. 4 seed in next week’s conference tournament. Naz Long scored all 14 of his points after the break while Melvin Ejim added 12 points and eight rebounds.

Marcus Smart finished with 27 points, five assists and four steals for Oklahoma State (20-11, 8-10), which saw its four-game winning streak snapped.

Oklahoma State turned a seven-point halftime lead into a 16-point advantage early in the second stanza before Kane scored six points during a 17-2 run to bring the Cyclones within one. Brown hit a 3-pointer and the Cowboys hit five straight free throws to temporarily hold off Iowa State, which rolled off 14 of the next 16 points to take a 63-57 lead with 4 1/2 minutes left after a pair of free throws from Niang.

Smart and Brown countered with the next nine points to put Oklahoma State back in front less than two minutes later, but the Cowboys could not close it out in regulation as they missed the back end of three straight trips to the foul line and Long made them pay when he drained a long 3-pointer as time expired. Kane scored half of his team’s 14 points in the extra period, including the go-ahead layup with 25 seconds left and three free throws to seal it.
