As a freshman, the Gators coaching staff decided to redshirt Martin and he worked as a member of Florida's scout team, winning the Gators' John Eibner Award, which is presented annually to the Gators scout team's "unsung hero." As a sophomore in 2002, he played in twelve of thirteen games, primarily as the backup to the starting quarterback, Rex Grossman, but he also served as the starting punter in seven games and played as a wide receiver in eight games. As a passer, he completed seven of ten passes for ninety-six yards, and also caught two passes for fourteen yards and rushed eleven times for fifty-one yards; as a punter, he averaged 35.2 yards on forty-six punts.
