– Buddy Hield and Oklahoma passed a major test Saturday night.

A bigger one awaits.

Hield scored 22 points and No. 3 Oklahoma beat No. 11 Iowa State 87-83 to match the second-best start in school history at 12-0.

On Monday night, the Sooners will play at No. 2 Kansas in what likely will be a No. 1-vs.-No. 2 showdown after No. 1 Michigan State lost to Iowa on Tuesday night.

"It's going to be fun," Hield said. "It's going to be a matchup that everybody's going to be watching. We're going there to handle our business."

The Sooners nearly slipped on the way to the dream matchup. Iowa State led for most of the second half, and Oklahoma led by two and had the ball in the final minute before turning it over. Iowa State's Monte Morris had a good look, but missed a three-pointer with 5.8 seconds to go. Hield made two free throws with 3.5 seconds remaining to put the game out of reach.

"As good a look as you're going to get, especially on the road," Iowa State coach Steve Prohm said. "I mean, a wide-open three."

Georges Niang scored 29 points, and Deonte Burton had 14 of his 19 points in the second half for Iowa State (11-2).

Hield's presence opened things up for his teammates. Ryan Spangler had 20 points and 12 rebounds, and Isaiah Cousins scored all 15 of his points in the second half for the Sooners in the Big 12 opener for both teams.

Cousins went 0-for-6 from the field in the first half. He missed two more in the second half before finally connecting.

"We know he's going to get it going for us," said Hield, who also missed four of his first five shots as Iowa State took an 18-9 lead. "Isaiah really stepped up and made some big plays when we needed them."

Oklahoma, the nation's top three-point-shooting team, went only 3-for-16 from long range in the first half but was 8-for-13 in the second.

"The second half was much more indicative of what we've done all year," Oklahoma coach Lon Kruger said. "We really haven't had a half like the first half. Credit Iowa State for that. But I think we contributed by not passing the ball as freely as we typically do. We've got to do a better job of that Monday for sure."

Iowa State shot 56.3 percent in the second half yet was outscored 50-42.

"It's just tough to take this one," Niang said. "I feel like we came in and played a great game."
