The Diamondbacks entered the 2002 season as the defending World Series champions.
However, they were unable to defend their World Series title as they were swept in the NLDS by the St. Louis Cardinals in three games.
Randy Johnson would finish the season as the NL Cy Young Award winner for the fourth consecutive year and become the second pitcher in history to win five Cy Young Awards after Roger Clemens.
