NORMAN, Okla. (AP)-- Oklahoma coach Lon Kruger had been searching for signs that his young, talented team was growing up.
He saw plenty on Saturday. Buddy Hield scored 22 points and Ryan Spangler added 16 points and a career-high 15 rebounds to help Oklahoma knock off previously unbeaten Iowa State 87-82 Saturday.
It was a big step for the Sooners, who had lost two of three and were coming off a 90-83 home loss to Kansas on Wednesday. Oklahoma knew it could score, but good defense in key moments had been absent.
"In the second half there, we got two or three stops we really needed," Kruger said. "We've been trying to learn how to do that."
Isaiah Cousins added 17 points for the Sooners (13-3, 2-1 Big 12), who ended No. 9 Iowa State's school-best winning streak at 14 games.
Kruger said the win against Fred Hoiberg's Cyclones was important. Iowa State was off to its best start ever, and many times in the second half, the Cyclones made the kinds of runs that have won them games this season.
"Huge win, obviously," Kruger said. "Fred does such a good job. They've got so many weapons. They space the floor and just make it awfully tough to guard. You've got to pick your poison sometimes. I'm really happy for our guys."
Spangler, a 6-foot-8, 232-pound sophomore, constantly outhustled Iowa State's more athletic big men.
"Ryan just took over the game," Kruger said. "Did some great things offensively and rebounded the ball like crazy. The guy gets so much respect for how he approaches it because he brings it every day and doesn't care about anything else except the team."
