Diamondbacks manager Bob Melvin
Early speculation had centered on third-base coach Chip Hale or bench coach Kirk Gibson, but general manager Josh Byrnes preferred a non-traditional hire in an attempt to shake things up.
The Diamondbacks are a very disappointing 12-17 this season. Since starting 20-8 last year, they have gone 74-89. Arizona, a talented young team that was looked upon as the biggest threat to the Dodgers in the NL West, has not hit. Another issue may have been D-backs prospects thriving after leaving the team, such as Carlos Quentin, and to a somewhat lesser degree, Emilio Bonifacio.
Under Melvin, the Diamondbacks improved 26 games in 2005 and won a National League-high 90 games in 2007 when they reached the NLCS.
