On March 31, 1998 the Diamondbacks took the field at Bank One Ballpark for the first time facing the Colorado Rockies.
Pitcher Andy Benes took the mound for Arizona and the birth of Major League Baseball in the desert was a reality.
The opening day line-up for that game included a mix of Expansion Draft players and free agents signed before the season.
The game ended in a 9-2 loss for the Diamondbacks in front of a crowd of 47,484.
