Wisconsin posted one of its worst offensive performances of the Bo Ryan era on Sunday, a 65-48 loss at No. 7 Oklahoma.
The Sooners held the Badgers to 23.5 percent shooting, the lowest since a 22.2 percent effort against North Dakota State in 2006 and the second-worst rate since Ryan took over in 2001.
"They played off of some of our guys who they didn't feel could shoot," Ryan said. "Actually, that would have referred to everybody on our team in the long run. When we had the opportunities in the paint, we didn't finish. I'm really disappointed in that."
Nigel Hayes had 20 points and 11 rebounds for the Badgers (4-3), who shot 7-for-33 on three-pointers and 9-for-35 inside the arc.
Ryan Spangler had 20 points and 14 rebounds for Oklahoma, making seven of nine shots. Isaiah Cousins added 14 points for the Sooners (4-0), who led for all but 30 seconds against last year's national runner-up. Buddy Hield, who averaged 25.3 points in his first three games, was held to 12 points on 5-for-16 shooting.
Iowa 84, No. 20 Wichita State 62: Jarrod Uthoff scored 22 points, Adam Woodbury had 15 and the Hawkeyes (4-2) defeated the Shockers (2-4) in the seventh-place game of the AdvoCare Invitational in Lake Buena Vista, Fla.
Mike Gesell added 14 points for Iowa.
Wichita State got 14 points from Eric Hamilton. Ron Baker, who entered averaging 20.2 points, was held to eight.
Wichita State again played without forward Anton Grady, who was at an area hospital recovering from what doctors believe is a spinal cord concussion that happened during a collision with an Alabama player in Friday's game. Doctors found no signs of spinal cord trauma.
Grady was released from Orlando Regional Medical Center on Sunday night and was set to fly home with the team. The school said Grady is walking with assistance.
"I have a lot of work to do to get back on the court, but with the help of such a great support system, I'm ready for the challenge," Grady said.
Wichita State senior guard Fred VanVleet sat out all three games of the tournament because of a hamstring injury.
