Where would he play? Desi's entrenched at SS. I don't see Davey moving Espi off 2B any time soon. Harper will be in CF once Werth comes back unless they move Morse in which case, I think Moore would/should get the LF job.
An outfielder would work, possibly Juan Pierre if the Phillies become sellers? Hes having a great year -- .320 avg with 20 steals -- and only has a 1 year contract. Downside is hes getting pretty old now.
