The D-backs hoped to contend for a postseason berth in what was a weaker National League West than in years past.
However, just three years after winning a World Series title, the Diamondbacks instead finished the season with a record of 51–111, the worst record by any National League team since the 1965 Mets won one fewer game.
The one highlight of a disastrous season was when Randy Johnson pitched a perfect game on May 18, 2004.
