AUBURN HILLS, Mich. -- Tim Hardaway Jr., Stu Douglass and the rest of Michigan's sharp shooters looked plenty comfortable playing at a faster pace.
Hardaway scored 18 of his 21 points in the second half, and the 20th-ranked Wolverines held off in-state rival Oakland 90-80 on Saturday. Michigan shot 70 percent in the second half in its highest-scoring game in over two years.
"I didn't think we were going to win a game like this all year," Douglass said. "Teams like [Oakland] score a bunch of points and we like to beat them 70 to 60, and kind of play that gritty Big Ten style a little bit."
Evan Smotrycz had 20 points and nine rebounds -- both career highs -- and freshman Trey Burke had 20 points and nine assists.
"Trey was unbelievable today," Hardaway said. "He just keeps on getting better."
Douglass finished with 13 points.

Reggie Hamilton scored 28 points for the Golden Grizzlies (6-4).
Michigan (7-2) shot 57 percent for the game and went 15 of 28 from 3-point range.
"Once they start going in, it may be a bit contagious," Michigan coach John Beilein said.
It was the highest-scoring game for Michigan since the Wolverines beat Northern Michigan 97-50 on Nov. 14, 2009. It was Michigan's first game with three 20-point scorers since Dec. 11, 2002, against Bowling Green.
The Grizzlies beat Tennessee both last season and this season and they've been dominant recently in the Summit League. They weren't intimidated by Michigan, recovering from a double-digit deficit in the first half to tie it at halftime.
The Wolverines were uncharacteristically careless in the first half, turning the ball over 10 times, but they were willing to play at a quicker place than usual against the Grizzlies.
Michigan went on a 14-4 run in the second half that included two 3-pointers by Hardaway and one each by Burke and Douglass. After Douglass made his, the Wolverines were 8 of 11 from long distance in the second half and led 66-55.
It was 73-67 after Hamilton made two free throws with 4:39 to play. Douglass answered with a free throw, and after Laval Lucas-Perry's 3-pointer rattled in and out for Oakland, Hardaway made a 3-pointer from the left corner.
A dunk by Douglass made it 79-67.
"I thought the game turned around late when Lucas-Perry had a 3 go three-quarters down and come out," Oakland coach Greg Kampe said. "They go down the other way and Trey Burke's falling out of bounds and throws it out to Hardaway for 3. We turn it over, they get a run-out layup and it is 12 instead of four."
It was 32-32 after a first half that lacked rhythm because of problems with the scoreboard. The game was played at The Palace, the home of the NBA's Detroit Pistons. It's not far from Oakland's campus.
The overhead scoreboard wasn't working, forcing a public address announcer to inform fans verbally of the score. There was also a short delay -- with Michigan ahead 25-13 - because of an apparent problem with the shot clock.
Oakland chipped away after that, eventually tying it on Travis Bader's 3-pointer in the final seconds of the half.
"It's very uncomfortable when you don't know the score," Beilein said.
That problem was fixed before the second half, and Michigan went on to its sixth straight victory in the series. Beilein has indicated the Grizzlies won't be on Michigan's schedule next season.
"We live in Michigan, and they are the University of Michigan, so obviously we want to play them," Kampe said. "He's got to do what is best for his program, and that's the decision he has made. I'm glad he was honest with me about it, even if I'm sad about the choice."
