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.
Am I the only one that thinks the Lombo/Espi platoon is working quite well? Their LH/RH splits are good... both are over .340 OBP against the pitchers they start against.
