ANN ARBOR, Mich. (AP) -- Glenn Robinson III scored 15 points and No. 7 Michigan pulled away in the second half to beat Division I newcomer UMass-Lowell 69-42 Friday night.
Michigan (1-0) raised its Final Four banner from last season before the game, but the River Hawks (0-1) actually led by two early in the second half. The Wolverines took control by scoring the game's next 21 points, and that was the end of the upset bid.
Michigan was without star big man Mitch McGary, who missed the game because of a lingering back problem.
The Wolverines looked out of sorts for a while in their first game after the departures of national player of the year Trey Burke and fellow guard Tim Hardaway Jr. Both left for the NBA after last season.
Akeem Williams scored 16 points for UMass-Lowell, which was making its Division I debut. The River Hawks aren't eligible for the America East or NCAA tournaments until 2017-18.
Caris LeVert led the Wolverines with 17 points and freshman Zak Irvin added 10.
The game was tied at 23 at halftime, and Williams made a layup off a steal for UMass-Lowell for the first basket of the second half.
The River Hawks went over 10 minutes before scoring again.
Jon Horford put Michigan ahead 27-25 with a dunk, and last season's NCAA tournament runner-up eventually put the game out of reach. Freshman Derrick Walton was fouled while shooting from beyond the arc and made all three free throws. That made it 32-25, and Irvin added a 3-pointer and two free throws to push the lead to 17.
It was 44-25 when DJ Mlachnik made two free throws for the River Hawks to end the scoreless drought.
The Wolverines raised their 2013 Final Four banner in a ceremony about 20 minutes before the game. It was a particularly meaningful moment for this program because the Fab Five-era banners from the school's previous two trips to the Final Four - in 1992 and 1993 - were taken down because of NCAA violations.
Walton, Burke's replacement at point guard, started in his first college game, and he made a nice pass to Nik Stauskas for an early 3-pointer that put Michigan ahead 8-0. Williams finally scored the first basket for the River Hawks with 14:27 to go in the half, and UMass-Lowell was able to keep it close for a while.
Early on, the Wolverines looked nothing like the smooth, efficient team that came within a few points of a national title last season. Michigan shot 6 of 23 from the field in the first half and 1 of 9 from 3-point range.
