NEW YORK — John Beilein gave his players one night to celebrate.

That's all the Michigan coach could afford.

After stunning No. 4 UCLA 55-52 in the semifinals of the 2K Sports Classic on Thursday night, the once-woeful Wolverines suddenly have a date with No. 10 Duke in the championship game.

"It was great, great for our team," Beilein said, "but we have a great opponent tomorrow."

A fitting opponent, too. The win was Michigan's first over a top 5 team since beating then-No. 1 Duke on Dec. 13, 1997.

The Blue Devils beat Southern Illinois 83-58 in the other semifinal of the tournament benefiting Coaches vs. Cancer.

DeShawn Sims scored 18 points and Manny Harris added 15 to lead the Wolverines (3-0), who shut down UCLA's offense with Beilein's lockdown, confusing 1-3-1 zone defense.

"We were just impatient. Sometimes we weren't aggressive enough, sometimes we were too aggressive," said Darren Collison, who led the Bruins with 13 points.

Michigan trailed 48-46 with 4:16 left when Stu Douglass hit a long 3-pointer to take the lead. Collison was stripped on the other end, leading to a layup by Sims that made it 51-48.

UCLA (2-1) cut the deficit to two when Josh Shipp made a free throw. After Michigan worked the shot clock down, Anthony Wright found Sims on a backdoor cut for a two-handed dunk that gave the Wolverines a four-point lead with 28 seconds left.

Nikola Dragovic's 3-pointer with 5 seconds to go cut it to 53-52, but Harris hit two free throws and blocked Collison's potential tying 3-pointer at the buzzer.

"When it got tight, we never hung our head down, even the younger guys," said Sims, part of a team that went 10-22 in Beilein's first year last season. "It shows how far we've come."

In other ranked games Thursday, it was: No. 13 Memphis 83, Chattanooga 71; No. 18 Florida 64, Southern Utah 50; and Seton Hall 63, No. 19 Southern Cal 61.

The Blue Devils also struggled early against Southern Illinois before finally taking control in the second half.

Gerald Henderson scored all 20 of his points after the break, and Jon Scheyer and Kyle Singler each added 13 as Duke (4-0) overcame 15 first-half turnovers.
