On March 31st with 50,179 fans overflowing Bank One Ballpark, the Arizona Diamondbacks play the first regular-season game in franchise history, against the Colorado Rockies. The Rockies would win the game 9-2, but not before Travis Lee collects Arizona's first hit (a first-inning single), first homer, first-run, and first RBI.

The Diamondbacks would get their first win on April 4th with a 3-2 victory over the San Francisco Giants. There was not much success for the first-year team their best play comes during a seven-game winning streak as August turned into September.

The D-backs would go on to finish in last place with a typical 65-97 expansion record.
