The Diamondbacks are shopping outfielder Gerardo Parra, an MLB executive tells ESPN.com’s Jerry Crasnick (via Twitter). The 27-year-old is earning $4.85MM in his penultimate season of arbitration eligibility.

Parra, who bats from the left side, was said to be an unlikely trade candidate, but it appears that Arizona’s stance has changed. Parra has struggled this year with a .256/.301/.358 line, while defensive metrics have soured on his work in the outfield. After posting 5.5 rWAR and 4.5 fWAR last year, he has been at or below replacement level in 2014.

Nevertheless, Parra could be attractive to teams given his ability to play center and track record of success. And while he will not be cheap next year, Parra should remain affordable in a market that handed eight-figure, two-year guarantees to players like Nate McLouth, Rajai Davis, and David Murphy.
