The Diamondbacks maintained their existing relationships with the seven minor league affiliates that began with the club in 2002.  This provided stability to the organization that was quickly amassing a great farm system despite drafting lower due to the parent club's success.  The affiliates for 2004 for the Arizona Diamondbacks are listed below.
