The Wolverines led just 32-30 at halftime despite 14 North Florida turnovers.

Sams made three 3-pointers early in the second half, then capped a 7-0 Ospreys' run with a lane jumper to give them their last lead at 47-46. Michigan regained the lead on a Robinson 3-pointer and stretched it out with more scoring from the senior swingman. He added another 3, a coast-to-coast layup, a dunk and two free throws over the next six minutes to give the Wolverines a 65-53 lead.

Wagner's three-point play gave Michigan a 20-point lead at 73-53 with 4:29 left.
