This weekend has been a busy one for fans of the Arizona Diamondbacks (59-49). Usually a seller at the MLB trading deadline, the D-backs went on the offensive in 2011, picking up Jason Marquis and Brad Ziegler to help shore up the pitching situation.

General Manager Kevin Towers is confident that the current offensive players on the roster are good enough to make the push to the postseason, giving a vote of confidence to Willie Bloomquist as the every day shortstop moving forward.

With the trade of Brandon Allen, the Diamondbacks will call up phenom Paul Goldschmidt from Double-A Mobile. It's a bold move by an organization that is playing for today while keeping a keen eye on the future.

The refusal to trade any of their top assets forced Arizona to look for bargain-basement pricing, and that's where Marquis and Ziegler came into play.

Everyone knows that this season has been a pleasant surprise in the desert. Ian Kennedy and Daniel Hudson stepped up and have contributed significantly as a 1-2 punch in the starting rotation, while Joe Saunders has pleased fans and management alike with consistent pitching since May.

Improvements to the rotation? Check. A solid seventh inning reliever? Check. An offense that has averaged over six runs a game in their past eight contests? Check.

Only two games back of the Giants with a three-game set beginning on Monday, Arizona could make a huge statement in AT&T Park. Ian Kennedy (12-3, 3.22) will face Matt Cain (9-6, 2.91) in a likely pitchers duel. Will Goldschmidt get his first MLB start?

With all the changes happening, one thing is for sure: the Arizona Diamondbacks will be contenders for the foreseeable future. Things are finally looking up for Phoenix sports, huh?
