Can Gerardo Parra keep up the pace?

One of the main reasons it was easy to be skeptical about whether Arizona Diamondbacks outfielder Gerardo Parra would be able to continue his exceptional season was the competition on his own team. After all, the Diamondbacks figured to use lefty hitting slugger Jason Kubel in left field, while rookie Adam Eaton would get on base and run and handle center field, and Cody Ross wasn’t given an exorbitant three-year contract to merely pinch hit. However, as May winds down none of Arizona's expected starting outfielders are playing a significant role for the team, if any at all, and Parra keeps on producing.
