Reserve Sam Dekker matched his career high with 19 points to lead No. 17 Wisconsin to a 77-46 victory over Nebraska on Tuesday night.

Ryan Evans added 14 points and Ben Brust had 13 for the Badgers (20-8, 11-4 Big Ten).

Dylan Talley had 21 points and eight rebounds for the Cornhuskers (13-15, 4-11), while Brandon Ubel added 10 points.

Wisconsin took control of the game early with a barrage of 3-pointers and then cruised to the blowout as Nebraska's offense disappeared.

The Badgers opened the game 8 for 11 from behind the arc, and five came in a spurt that turned a 10-8 deficit into a 35-14 lead. Dekker accounted for 11 points in the 27-4 run, including three 3s.

Nebraska, meanwhile, made just one of its first 18 shots from the field to open the second half, scoring just three points over a more than 11-minute stretch.
