It'd have to be one hell of an injury to keep Martin out long, a back up at league minimum is better spent for half a win, on insurance, he's too pricey. Kratz could put up the same WAR for the 150-175 AB's for Dickey starts, as would Navvy for Estrada starts. Not to mention our offense is more than capable to carry an injury to Martin if he goes down. That cash could go towards an SP/RP or whatever. I agree about Dioner though, he isn't terrible, just too expensive.
