– Iowa State coach Fred Hoiberg wouldn't have wanted it any other way. The Cyclones had a one-point lead and leading scorer Georges Niang throwing the ball inbounds with less than 20 seconds left.

But 6-foot-7 Kansas State forward Wesley Iwundu had another outcome in mind.

Iwundu capped a 22-9 scoring run with a steal and two-handed slam that gave Kansas State a 70-69 win over No. 12 Iowa State on Saturday and back-to-back Top 25 wins.

­"It's tough," Hoiberg said. "You put the ball in your best player's hands, and I trust Georges is going to make the right play 99 percent of the time."

Kansas State (15-15, 8-9 Big 12) tied the score at 66 apiece with a tip-in by Justin Edwards with 59.4 seconds left. Iwundu gave Kansas State a 68-66 lead 13 seconds later,. The Cyclones responded with a three-point play by Monte Morris.

Iwundu's steal and slam proved redemptive after the sophomore had missed a free throw. He finished with 11 points.

The Wildcats held Iowa State (20-8, 10-6) to 38 percent shooting in the second half, which followed 8-of-15 shooting from three-point range in the opening 20 minutes.

"They pressure the heck out of you in this building, there is no doubt about that," Hoiberg said.

Nigel Johnson led Kansas State with 17 points after scoring a career-high 20 points in an upset of No. 8 Kansas on Monday night.

"He's been way more focused and playing with a lot more confidence," Iwundu said of Johnson.
