I give: Dan Haren
I get: Ryan Zimmerman
The guy also has Evan Longoria so I wouldn't need to compensate him with a 3B. I dont know much about Zimmerman's injury though, is it something too worrisome to trade away an ace for?
I would then most likely drop Mark Reynolds and pick up one of Daniel Hudson, Madison Bumgarner, Alexi Ogando, or Anibal Sanchez from the FA pool.
Oh and I also have Roy Halladay, Ricky Nolasco, Jhoulys Chacin, Jeremey Hellickson, Francisco Liriano, and Bud Norris as my SP's
