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 with a free throw 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 eight feet.

The Cyclones knocked the ball out of the hands of Kansas State’s Will Spradling at the buzzer.

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

What appeared to be a pending Kansas State blowout developed into a crushing loss for the Wildcats.

Iowa State opened the second half looking out of sync, and the Wildcats took advantage of that sluggishness by expanding their lead to 14 points. Jamar Samuels capped a 10-2 run with a three-pointer from the corner with 14:27 left, putting Kansas State ahead 53-39.

The deficit got the Cyclones’ attention, and by the midway point of the second half they’d cut it to 57-51 on a dunk through traffic by White. Allen made it a 60-58 game with a 3-pointer before Spradling answered with a three of his own with 7:11 left.

Samuels, Rodney McGruder and Martavious Irving each scored 11 points for Kansas State.
