Madison, Wis. — With his team leading by double digits at halftime, Wisconsin's Josh Gasser tried to give his team some extra motivation in the locker room.
Don't let up and play hard the full 40 minutes, he pleaded.
The sixth-ranked Badgers listened to their senior leader. Frank Kaminsky had 13 points and 11 rebounds, and Wisconsin relied on tough defense to rout No. 25 Iowa 82-50 on Tuesday night.
"I thought we played a good first half. We've done that before," Gasser said. "We wanted to play a good 40 minutes for once."
The Badgers (17-2, 5-1 Big Ten) led by 18 at the half by going 6 of 14 from 3-point range and holding Iowa (13-6, 4-2) to 7 of 25 from the field (28 percent).
Wisconsin finished off the Hawkeyes with a strong performance on the glass, with nine of 15 offensive rebounds coming in the second half.
Sam Dekker added 17 points and eight boards for the Badgers, who won their second straight since losing starting point guard Traevon Jackson to a foot injury.
Jackson's replacement, Bronson Koenig, shot 3 of 6 from 3-point range and finished with 13 points.
The relaxed Badgers were in a jovial mood after the blowout win over one of the league's other top teams. At one point in the postgame news conference, Kaminsky referred to Gasser as "Captain America."
Gasser left the court for about 3 minutes in the second half after holding his left arm in pain. He was cleared to return after an exam in the locker room.
"Josh is Captain America. Josh is the hero of our team," Kaminsky joked.
Jarrod Uthoff, a Wisconsin transfer, had 12 points for the Hawkeyes. Iowa lost its first road game of the season.
"Anything short of a complete effort and concentration, you're going to struggle to win this game," Iowa coach Fran McCaffery said.
Wisconsin opened a 23-11 lead with 6:35 to go in the first half on Dekker's second 3.
Iowa turned to a 2-3 zone, trying to slow down the shooters. But the Badgers are pretty good against the zone, too, since their forwards also can handle the ball well.
On the next two possessions, the Badgers got the ball to Hayes, who was stationed near the foul line in the middle of the zone. Hayes found cutters to the basket who were fouled each time for free throws.
Dekker had a scooping layup later off a baseline move, before Kaminsky riled up the Kohl Center crowd with a dunk to make it 35-17 with 6 seconds remaining in the half.
More Big Ten
(At) Nebraska 52, Minnesota 49: Shavon Shields scored 13 of his 15 points in the second half and Nebraska survived an eight-minute field-goal drought to end the game to beat Minnesota.
The Cornhuskers (11-7, 3-3 Big Ten) made 11 of their last 12 free throws after starting 3 for 9 from the line. Benny Parker made two with 25 seconds left to make it a three-point game, and the Gophers missed three straight 3-pointers before the final buzzer.
Minnesota (12-8, 1-6) has lost six of its last seven games. Five of the Gophers' six conference losses have been by five points or less.
Terran Petteway added 11 points for the Huskers in a slog of a game that had 33 field goals and 31 turnovers.
(At) No. 1 Kentucky 65, Vanderbilt 57: Kentucky twin guards Aaron and Andrew Harrison combined for 11 points down the stretch that were key. The Wildcats (18-0, 5-0 Southeastern Conference) didn't lead by double digits until early in the second half, and that 45-33 advantage lasted briefly as the Commodores (11-7, 1-4) began answering from the perimeter to stay within several possessions of Kentucky.
(At) No. 9 Iowa State 77, Kansas State 71: Monte Morris hit a floater with 37 seconds left and No. 9 Iowa State held off Kansas State, moving into a tie for first place in the Big 12.
Jameel McKay had 15 points off the bench for the Cyclones (14-3, 4-1), who joined No. 11 Kansas atop the league. Iowa State beat Kansas in Ames 86-81 on Saturday.
Kansas State turned it over at mid-court after Morris put the Cyclones ahead 73-69. That miscue allowed Iowa State to seal the game at the line.
Nino Williams had a season-high 22 points for Kansas State (11-8, 4-2), whose winning streak was snapped at four games.
(At) Davidson 77, No. 22 Dayton 60: Freshman Peyton Aldridge had 22 points and senior Tyler Kalinoski added 21, and the sharp-shooting Davidson Wildcats knocked off No. 22 Dayton 77-60 on Tuesday night for their first win over a ranked opponent this season.
Davidson was 12 of 23 from 3-point range, helping to erase a 26-point loss to Richmond three days earlier.
Aldridge and Kalinoski were both 9 of 14 from the field and combined to shoot 7 of 9 from beyond the arc.
