ANN ARBOR, Mich. — Michigan's basketball program has been hibernating for a decade.

It looks like the Wolverines are finally waking up.

DeShawn Sims scored a career-high 28 points to lead Michigan to an 81-73 victory over Duke yesterday, its second win over a No. 4-ranked team in two weeks.

The Wolverines (6-2) beat then-No. 4 UCLA before losing 71-56 to Duke in the 2K Sports Classic final.

Michigan — which hasn't been to the NCAA tournament since 1998 — has beaten two top five teams in the regular season for the first time since 1986-87, the year after its last Big Ten title.

"I still think it's a rebuilding year," Sims insisted. "Even though we've had two big wins, we've also lost two games. It definitely says we're executing what Coach wants us to do on both ends of the court."

Manny Harris scored 17 points for the Wolverines and reserve freshman Zack Novak had a season-high 14, connecting on consecutive 3-pointers to give them the lead for good with 7 1/2 minutes left.

Sims, a junior forward, matched a career high with 12 rebounds.

Duke (8-1) made just 3 of 27 3-point attempts before connecting on four in a row to pull within four points in the final minute. The Blue Devils finished 7-of-33 for one of their worst performances beyond the arc in more than a decade.

"Michigan did a good job with the 1-3-1 zone," said Duke's Nolan Smith, who matched the team high with two 3-pointers and finished with 12 points. "They extended it to take away 3s in the corners and on the wings."

The Wolverines made 13 of 14 free throws in the final 3 minutes to seal the upset, leading to hundreds of fans from the sold-out crowd rushing the court.

"I'm at a little bit of a loss for words," second-year Michigan coach John Beilein said. "That was a great atmosphere, wasn't it?"

It was as great as it was rare.

After an 11th lead change and 16th tie, Novak's second straight 3-pointer led to Duke calling a timeout with 7:39 left to calm down a raucous crowd that's characteristically quiet in a community consumed by football.

"I saw the Savannah State tape and there weren't too many seats full," said Duke coach Mike Krzyzewski, referring to the previous home game that had an announced crowd of 8,190 in an arena that holds almost 14,000. "It's party time every time we come to town, but this is a great school and they deserve this level of support for every game."

Duke had won 31 straight games against unranked, nonconference opponents dating to a loss against Georgetown on Jan. 21, 2006.

No. 3 Pittsburgh 80, Vermont 51: Sam Young scored 28 points, DeJuan Blair added 13 points and 16 rebounds, and the Panthers (9-0) raced to a 13-0 lead en route to a 41-19 cushion at intermission in cruising past the Catamounts (4-3) at Pittsburgh.

"Coach (Jamie Dixon) told us it's time to test where our defense is to get us ready for the great teams," Young said, referring to a Big East Conference that has eight of this week's Top 25 teams.

No. 5 Gonzaga 70, Indiana 54: Josh Heytvelt scored 17 points, Jeremy Pargo added 13 and the visiting Bulldogs (6-0) came to Indianapolis and forced 25 turnovers to beat the Hoosiers (4-4), who lost for the third time in 12 days to a team ranked in the top 20.

"After (upsetting) Miami, we talked about how that game gets us no points against Notre Dame," Ohio State coach Thad Matta said. "But we talked about the challenge and the opportunity we had this week. ... We got better this week, but by no stretch are we where we want to be."

No. 11 Louisville 83, Indiana State 43: Earl Clark had 16 points and 10 rebounds, and Terrence Williams added 12 points, eight rebounds and seven assists as the Cardinals (3-1) forced 23 turnovers to overwhelm the Sycamores (0-6) at Louisville, Ky.
