Iowa State had one of those no, no, yesssss moments with less than a minute to play against 23rd-ranked Oklahoma Saturday afternoon at Hilton Coliseum. But with the way Georges Niang played the first 39 minutes, why not?

So with 55 seconds to play and the 16th-ranked Cyclones leading by a 3-pointer, Niang found himself open.

Four corners offense? Not for this Iowa State team that mostly doesn’t like wasting precious ticks from the clock, regardless of the score.

So Niang fired away almost 5 feet beyond the 3-point arc with the game on the line. It ended up being the biggest of his 10 baskets during the Cyclones’ 81-75 victory before 14,384 fans who not only cheered that, but also Niang’s career-best offensive game. Both resulted in a confidence-builder heading into Monday’s 8 p.m. game at eighth-ranked Oklahoma State, where the Cyclones have an 18-game losing streak.

“What was I thinking, huh?” Niang said of his late 3-pointer. “I completely zoned out. I stepped into a shot that I thought was a good one. Lucky for me it went in.”

Iowa State’s records improved to 4-4 in the Big 12 Conference and 16-4 overall, while Oklahoma fell to 6-3 and 17-5.

“Niang kept making big plays when they needed them,” Sooners coach Lon Kruger said.

“Iowa State played great and deserved to win.”

Niang scored 27 points, three better than his previous best, before fouling out with 28 seconds to play. Conference scoring leader Melvin Ejim followed with 22 points and 16 rebounds, while Matt Thomas scored 13.

Oklahoma’s Buddy Hield led all scorers with 30 points, but mustered just five free throws during the final 15:52 of the game. He made 10-of-18 shots, including 10-of-15 before being shut down.

“I could have done more to help my teammates,” Hield said.

The Cyclones were able to contain Hield by shifting their defensive attention from double-teaming Ryan Spangler in the post to staying with Hield on the wings.

“We told him to stop shooting,” Niang said, joking. “He was feeling it. When we got to him and made him shoot tough shots, we did a better job.”

Iowa State got revenge for an 87-82 loss at Oklahoma on Jan. 11, when the Sooners had a whopping 22-2 advantage on second-opportunity points. That didn’t happen Saturday — they got just four second-chance points, and none after the teams went into halftime tied 37-37.

“Throughout the game, we had some opportunities that we didn’t finish,” Kruger said.

That became a focus in practices after Wednesday’s loss at Kansas.

“They still got us on the glass by 13, but not as many second-chance points,” coach Fred Hoiberg said. “We did a better job.”
