Clarence Diskerson's 21-foot jumper with one second to play gave Hawaii a 62-61 victory over Michigan State in Honolulu.
Earlier, Cal State-Fullerton edged Bradley, 64-62, for seventh place when center George Hawthorne made a turnaround jumper with three seconds left. Later, 20th-ranked North Carolina State was to play unranked Rice in the championship game after No. 2 Wichita State and No. 6 San Francisco met for third place.
Four points by Rodney Jones closed the Rainbows (7-2) to 51-50 and the one-point lead changed three times in the final minutes until Derek Perry's 14-footer put Michigan State (5-5) ahead, 61-60, with 21 seconds remaining.
Dickerson in-bounded the ball with six seconds left, ran along the base line to the opposite side of the court, took a return pass from Jones and shot as the buzzer sounded.
David Thirdkill's layup and a 20-foot jumper by Eddie Matthews gave Bradley (6-6) a tie at 62 with 26 seconds left. The Titans (6-7) held the ball for a last shot, and Hawthorne, who had eight points and a game-high 12 rebounds, scored from six feet to give Fullerton State its first victory of the tournament.
Thirdkill, who led all scorers with 22 points, and Mitchell Anderson, who had 14, led a surge put the Braves ahead, 46-38, midway through the second half. The Braves then missed nine consecutive shots, and the Titans, with Darrell Vetter making four free throws and Gary Davis getting two buckets, went on a 12-4 spurt. Another Davis jumper and two free throws by Leon Wood put Fullerton State ahead by four with 56 seconds to play.
