2002 Arizona Diamondbacks season

The 2002 Arizona Diamondbacks looked to repeat as World Series champions. They looked to contend in what was once again a strong National League West. They finished the season with a record of 98–64, good enough for the division title. 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.
