AMES, Iowa — Royce White hit the game-winning jumper with 1.8 seconds left as Iowa State rallied from a 14-point deficit to beat Kansas State 72-70 on Tuesday night.

White finished with 22 points and Chris Allen had 15 for the Cyclones (16-6, 6-3 Big 12), who've won four of their last five.

Iowa State's Chris Babb tied the game at 70 on a pair of free throws with 49 seconds left. The Cyclones then corralled a loose ball to gain possession with the shot clock off, and White drove to the baseline and floated in the deciding bucket from about 8 feet.

The Cyclones knocked the ball out of the hands of Kansas State's Will Spradlin at the buzzer.

Thomas Gipson led the Wildcats (15-6, 4-5) with 13 points.
