AMES, Iowa — Oklahoma got a career game from Buddy Hield, outrebounded Iowa State by 13 and had Isaiah Cousins deliver his first career double-double Saturday afternoon.
But it wasn't enough to overcome another off game by Cam Clark, big games from Iowa State's Georges Niang and Melvin Ejim and the Sooners not being able to take advantage of second chances.
Niang and Ejim combined for 49 points as the No. 16 Cyclones held off the No. 23 Sooners 81-75 in front of 14,384 at Hilton Coliseum.
Hield had a career-high 30 points, hitting five 3-pointers.
Niang led the Cyclones with 27 points, and Ejim added 22 and 16 rebounds.
“Ejim's had a terrific season,” Sooners coach Lon Kruger said. “Every time you watch them, it seems like he's going like that. He's a really good player, very versatile, tough matchup, rebounds the ball like crazy.”
The Sooners (17-5, 6-3 Big 12) had a four-game winning streak snapped.
Oklahoma will play at West Virginia at 6 p.m. Wednesday.
Iowa State (16-4, 4-4) looked ready to bury the Sooners with less than six minutes left when Monte Morris converted a turnover by Tyler Neal into a layup at the other end to put the Cyclones up by nine.
The Sooners wouldn't go away, though. Over the next three minutes, Oklahoma reeled off a 10-2 run.
Even in that run, though, the Sooners left chances on the table.
Freshman point guard Jordan Woodard missed a layup after he grabbed a rebound and went end-to-end. A basket would've pulled the Sooners within five. Instead, Ryan Spangler was called for a foul on the rebound try, and the Cyclones got their only points in the stretch on the resulting free throws.
The Sooners cut the lead to one on a pair of Hield free throws with less than three minutes left and got the ball back with a chance to take the lead for the first time since late in the first half after Clark swatted the ball away from Ejim in the lane.
But Hield couldn't keep the magic going. His fall-away jumper missed the mark, Clark was called for a foul with 1:58 to play and the Cyclones started extending the lead again.
Niang delivered the dagger, hitting his third 3-pointer of the game with just less than a minute remaining to all but end it.
Isaiah Cousins had 13 points and 10 rebounds and Woodard had 10 points — all after halftime. Spangler finished with 12 rebounds as the Sooners outrebounded Iowa State 46-33.
Oklahoma had 14 offensive rebounds but just four second-chance points. The Cyclones converted six offensive rebounds into eight points.
“Always when you get an offensive board, you'd like to finish it with a bucket,” Kruger said. “I thought throughout the game we had some opportunities that we didn't finish. We just have to slow down just a little bit and finish some opportunities that are there and be a little more efficient.”
Clark had seven points for the second consecutive game after scoring in double figures for 16 of the first 20 games.
