Argentina had the most impressive dunk and even held a lead. Everything else, however, went the way of the United States in a 103-72 victory tonight in the Olympic qualifying tournament.

Kevin Garnett scored 21 points, Tim Hardaway made five three-pointers and scored 20, Tim Duncan had 14 and Vin Baker, Jason Kidd and Allan Houston added 11 apiece for the Americans, who trailed for the first time in this tournament when Argentina took a 5-4 led with 17 minutes 32 seconds left in the first half.

From there, the United States used runs of 8-0, 16-0 and 10-3 to take a 30-point halftime lead.

Andres Nocioni of Argentina had the dunk of the night, driving around Garnett on the baseline and then going under the basket for a reverse slam over the outstretched arms of Garnett and Duncan.

The crowd went wild, giving the 19-year-old Nocioni an extended standing ovation. Even Garnett and Duncan appreciated the move, smiling broadly as they walked off the court during the ensuing timeout.

Nocioni tried to dunk over Garnett one more time just before the final buzzer, but Garnett rejected the shot and committed a foul. The two smiled and slapped hands before Nocioni, who plays professionally in Argentina, made 1 of 2 free throws for the final margin.

Argentina also had the first four-point play of the tournament against the Americans on the play immediately after Nocioni's dunk. That cut the Americans' lead to 72-40 early in the second half. Garnett followed with a dunk, one of his four, and Hardaway had a three-pointer to increase the lead to 37.

Tom Gugliotta did not play for the United States because of pain from a broken nose.

In an earlier game, Canada defeated Uruguay, 80-62.
