Nate Mason scored 31 points and Eric Curry scored seven of his 10 in overtime as visiting Minnesota upset No. 15 Purdue, 91-82, on Sunday.
The Big 10 teams traded baskets to begin the extra period before a Curry basket began an 11-0 run that helped snap the Boilermakers' seven-game winning streak.
Purdue's P.J. Thompson, who spent most the game trying to guard Mason, praised Minnesota's leading scorer, who came in averaging 13.5 points.
"He's a good player," Thompson said. "He came out ready to play and had his team ready to play."
The Golden Gophers (13-2, 1-1) allowed Caleb Swanigan to score 28 points and grab 22 rebounds, but it wasn't enough to save the Boilermakers (12-3, 1-1).

Kyron Cartwright scored 26 points and Rodney Bullock added 17 for Providence (10-5, 0-2). The Friars scored the game's first basket and led, 2-0, for a total of 39 seconds. Providence wouldn't lead for the rest of the game.
