Frank Kaminsky scored 8 of his 22 points in overtime to help Wisconsin avoid the upset. It was Derrick Walton Jr.'s 3-pointer with a second left that sent the game into the extra session. The Badgers led by 7 at the half, and 11 in the second half, before Michigan rallied to tie it.
Walton finished with 17, while Zak Irvin added 12 for a Wolverines team who is playing without star Caris Levert. Levert will miss the remainder of the season with a broken foot.
Sam Dekker scored 15 points for Wisconsin, who ran their record to 18-2, 6-1 in the Big Ten.
The Wolverines scored 11 straight points in the second half to tie the game. Wisconsin was unable to hold off the Wolverines rally, going just 7-of-21 from 3-point range. After remaining close for much of the 1st half, the Badgers got 2 three-point plays and a 3-point shot to break it open heading into the locker room.
The Wolverines fell to 12-8 on the season and 5-3 in Big Ten play, and they will host the Nebraska Cornhuskers on Tuesday. Nebraska got an impressive home win over the Michigan State Spartans Saturday afternoon. Meanwhile, the Badgers will visit the Iowa Hawkeyes next Saturday. Iowa was upset against the Purdue Boilermakers on Saturday.
