LAHAINA, HA (AP) -- Tim Hardaway Jr. had 21 points, Trey Burke added 14 and No. 15 Michigan knocked off No. 8 Memphis 73-61 in the opening round of the Maui Invitational on Monday.

Back in Maui for the first time since 1998, Michigan (4-0) looked right at home in paradise, using its ability to penetrate to shoot 54 percent while hounding the Tigers with a variety of defenses.

The two-time tournament champions move on to face No. 6 Duke in Tuesday's semifinals.

Memphis (1-1) backed up an easy season-opening win with a shaky performance against the experienced Wolverines.

Charles Carmouche led Memphis with 14 points.
