NEW YORK — Showing poise down the stretch and playing stellar defense, Michigan pulled off its first win over a top-five team in 11 years.

DeShawn Sims scored 18 points, including an emphatic dunk on a backdoor cut with time running down, and Manny Harris added 15 as the Wolverines upset No. 4 UCLA, 55-52, last night in the 2K Sports Classic.

"We knew we had an opportunity to win the game and in the past we had lapses down the stretch," said Sims, a junior forward. "It's the biggest win I've had at Michigan. This team is rebuilding and it's not going to stop."

The Wolverines' last victory over a top-five team came in 1997 against No. 1 Duke — Michigan's opponent in the championship game tonight. The 10th-ranked Blue Devils beat Southern Illinois, 83-58, in the first semifinal at Madison Square Garden.

With his team trailing 48-46 with 4:16 left, Stu Douglass hit a long 3-pointer to give Michigan the lead. Darren Collison was stripped on the other end, leading to a layup by Sims that made it 51-48 Wolverines.

UCLA (2-1) cut the deficit to two when Josh Shipp made one of two free throws with 56 seconds left. After Michigan (3-0) worked the shot clock down, Anthony Wright found Sims for a two-handed slam that gave the Wolverines a 53-49 lead with 28 seconds left.

The Bruins (2-1) weren't done. 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. No. 10 Duke 83, Southern Illinois 58: Gerald Henderson scored all 20 of his points in the second half, helping the Blue Devils (4-0) beat the Salukis (2-1) to reach the final of the 2K Sports Classic.
