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.
