The 2007 USA Basketball U 19 World Championship Team (3-0) is undefeated coming out of preliminary pool play after eeking out win over host team Serbia.
From Whole Hog Sports:
With time running off the shot clock, Arkansas rising sophomore Patrick Beverley had no choice but to put up a basket and his floater beat the 24-second buzzer, essentially putting the nail in the coffin with only 10. 1 ticks remaining. Serbia attempted a three, but Beverley, who scored 11 points, was there for the board to seal the win.
