I'd agree on Zimmerman but I'd be worried about his innings limit. He was last year but he should go longer this year,possibly all season. I own Dempster(3rd time) and he is on a roll. I'm hoping if he's traded it will be to LA because he might pitch better in NL WEST parks(except Coors,of course). Tough choice but I would go with Zim but investigate further if dempster lands in LA. Good luck!
