He's fallen out of favor in Arizona, with the acquisition of Jason Kubel. Parra hits for average, gets on base at a decent clip, can steal some bases and plays above average defense. Plus he's under team control through the 2015 season.
Should Sandy make a play for Parra and make him our CF?
Torres is far from a sure thing. Nieuwenhuis probably isn't an MLB CF, Den Dekker is a defensive whiz, but still needs seasoning. He could provide a lot of value on the cheap.
