Perhaps the biggest highlight of his career occurred against the Washington Wizards on March 30, 2007 in a game that helped determine the two teams' playoff seeding. The Raptors trailed 109–106 with only 3.8 seconds left and no timeouts remaining. The Wizards' Michael Ruffin intercepted the full-court pass and tried to toss the ball high into the air so that the clock would run out. But the ball slipped from his hands and was not thrown high enough. There was still enough time on the clock as Peterson caught the ball and launched a "Hail Mary" three-pointer and sank it to send the game into overtime. Peterson only played 55 seconds in the game, with his first shift beginning with only 9.3 seconds left in the fourth quarter. The Raptors went on to defeat the Wizards, 123–118.
