The defending NL West champion Arizona Diamondbacks don't have much to complain about entering the 2012 season.
With a starting rotation of Ian Kennedy, Daniel Hudson, Josh Collmenter, Trevor Cahill and Joe Saunders, the D-Backs are a threat to win games no matter who is on the mound.
Sporting a very solid batting order with everyday players at every position (including veteran leadership off the bench by way of Willie Bloomquist, Henry Blanco, Geoff Blum and John McDonald), the Diamondbacks appear poised to make a run at defending their division crown.
Nevertheless, contributions from players outside of the 25-man active roster become paramount during the course of a 162-game season. Injuries are a part of the game, just ask Stephen Drew. However, how teams overcome those injuries can often be the difference between a playoff team and a team that misses the opportunity to play in October.
Here are eight players that may make contributions to the Diamondbacks during the 2012 season.
