Arizona Diamondbacks

With Opening Day quickly approaching, only three National League teams have a better winning percentage than the Arizona Diamondbacks. However, they sit in the middle of the Cactus League standings. Wins say a lot during the regular season, but we need to look deeper to find meaning in those numbers during spring training.

Adam Eaton, considered among the most exciting young players in baseball, was expected to start in center field and bat leadoff for the Arizona Diamondbacks this year. Instead, it was recently announced that he will miss up to the first two months of the season because of injury. 

The grass is cut, the skies in Arizona are clear and the temperatures are perfect. It's time for baseball again in the valley of the sun, which means the Arizona Diamondbacks can put a disappointing 2012 season behind them and start fresh for 2013.

The Arizona Diamondbacks have extended the contract for newly acquired infielder Cliff Pennington, keeping him in Phoenix on a two-year, $5 million deal. The signing was reported by Buster Olney of ESPN via his Twitter feed.

The Arizona Diamondbacks are primed to make a run at the defending MLB champion San Francisco Giants and the free-spending Los Angeles Dodgers in the National League West. 2012 was a letdown, but 2013 is going to be a major rebound year.

No player has been mentioned in more trade rumors this offseason than Justin Upton—and with good reason.

The struggle between players and management has gone on since the beginning of the sports world. Each side wants to have leverage when the inevitable split occurs. The "no-trade clause" is one of the biggest assets a baseball player can have, and Justin Upton just used his to really affect the Arizona Diamondbacks.

A new rumor involving the Arizona Diamondbacks trading outfielder Justin Upton seems to surface daily. MLBTradeRumors.com is updating constantly with the latest potential landing spots for the sometimes brilliant and sometimes enigmatic right handed slugger.

In Kevin Towers' first season as the general manager of the Arizona Diamondbacks, he orchestrated a worst-to-first turnaround that brought the team from 65 wins to 94—a 29-win improvement good enough for the NL West crown in 2011.
