Since 2000, the Diamondbacks Foundation has built or refurbished 42 baseball fields and softball as part of the "Diamonds Back" Youth Field Building Program. With the aid of the "Diamonds Back" corporate sponsor, APS, local businesses, and monetary donations from individual players, this program has allowed children from across the state to play baseball and softball at quality facilities.

The fields generally feature new lights, an electronic scoreboard, new fencing and backstops, new irrigation and new dirtwork and/or grass. The locations of the fields are determined through a grant process.
