Junior guard Kenny Smith hit two free throws with three seconds remaining yesterday in Milwaukee to give top-ranked and unbeaten North Carolina a come-from-behind 66-64 victory over Marquette.

The Tar Heels (19-0) trailed by nine points with a little more than four minutes remaining before their pressure defense keyed a comeback in front of a sellout crowd at Milwaukee Arena and a national television audience.

Smith made both of his pressure-packed free throws despite the noisy and sometimes unruly crowd, which threw several objects on the court during the game. A penny hit Smith on the side of the head after the first free throw.

"You just have to go up there and concentrate," Smith said. "It's just you and the basket."

Smith scored North Carolina's last five points. "We put the game in Smith's hands at the end, and he came through," said North Carolina Coach Dean Smith, who also was hit with a penny from the crowd.

"I got hit by a penny at the end, and let me tell you that hurts," Dean Smith said. "I wanted the officials to call a technical on the crowd, but if they would have they would have never gotten out of here alive."

North Carolina's Brad Daugherty led all scorers with 20 points. Michael Sims scored 12 of his 16 points in the second half to lead Marquette (11-5).
