approach Minnesota about Glen Perkins and Ryan Doumit (both of whom have reasonable contracts for the next 2-3 years)....they need starting pitching,we'd be taking some salary off their hands....Perkins has been very effective in the pen and Doumit upgrades us offensively at a position of minimal offensive contribution for us.....
i'd offer some combination of Gee,Edgin,Turner or Marte...they'd be getting a starter,starting second baseman they'd have control over,plus Edgin who could replace Perkins over the next year or so
roster move would be to bring up Matt Harvey,he appears to be ready and has pitched well in a number of his most recent starts
(other relievers i'd take a look at would be Matt Belisle from Colorado and Brayan Villareal from the Tigers,Detroit is desperate for starting pitching and is in wild card race....)
just an idea
