NORMAN, Okla. -- Ryan Spangler had 20 points and 14 rebounds to help No. 7 Oklahoma beat Wisconsin 65-48 on Sunday.

Spangler made 7 of 9 shots, including 2 of 3 3-pointers, and fell just short of his career high of 21 points.

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.

Nigel Hayes had 20 points and 11 rebounds for the Badgers (4-3), who had won their previous two games. Wisconsin made 7 of 33 3-pointers but hit just 9 of 35 shots inside the arc.

The Sooners held the Badgers to 23.5 per cent shooting, Wisconsin's worst shooting performance in a game since a 22.2-per cent effort against North Dakota State in 2006.

Spangler scored 10 points in the first 7:13 to help the Sooners take a 15-3 lead.

Oklahoma led by as many as 17 points in the first half, and was up 34-19 at the half behind Spangler's 12 points, Cousins' 10 and Hield's eight. Oklahoma held the Badgers to 20 per cent shooting and Hayes to just five points in the first half.

Wisconsin rallied early in the second half, and Bronson Koenig's 3-pointer cut the Sooners' lead to 36-27. But Oklahoma regained control, and a layup by Spangler put the Sooners ahead 52-35 with 7:33 to play.
