 As the second half of the season approached, fans writing on various Diamondback fan blogs expressed opinions ranging from frustration with the players and coaching staff (especially Melvin, who is seen by many fans as having too casual and relaxed of an attitude to properly motivate the players) for what they see as the squandering of a potential NL West Championship season, to frustration with fellow fans for not being patient and allowing a highly talented current core of younger players, including Stephen Drew, Carlos Quentin, Micah Owings and Scott Hairston, to develop in the minor league farm system and contribute to the D-Backs success in later years (and possibly as soon as this season).On July 9, the Diamondbacks announced an agreement with manager Melvin on a two-year contract extension with an option for the 2009 season.On July 15, shortstop Stephen Drew was called up from the Sidewinders to replace Craig Counsell, who broke a rib during an at-bat on July 14.
