MADISON, Wis. (AP) -- Ethan Happ scored underneath the basket with 10 seconds left and Wisconsin beat No. 4 Michigan State 77-76 on Sunday.
The Spartans had a final chance to win but Denzel Valentine missed a 3-pointer and Matt Costello's last-second side jumper bounced off the rim.
Bronson Koenig scored 27 points and Nigel Hayes added 25 for the Badgers (10-9, 2-4 Big Ten), who trailed 76-72 after Valentine hit a runner for the Spartans (16-3, 3-3). Koenig hit a 3-pointer with Valentine in his face and the shot clock winding down to pull Wisconsin within 76-75 with 27 seconds left.
The Badgers went to a full-court press for the first time in the game, and forced a turnover as Eron Harris stepped out of bounds while double-teamed.
With the clock winding down, Koenig found Happ for the winning basket.
Valentine led Michigan State with 23 points, while Costello added 18.
