It all depends on the pitcher. I wouldn't do Encarnacion alone for Meche, let alone throw in Kearns and Bailey to add a 2B and a prospect. If it were a name top of the rotation stud like Harden or someone of similar potential, I'd go for it.
What if it's Zito and Meillo plus a PBTNL? Zito's certainly a name starter, but I'm a little gun-shy aroung him.
It would leave you with Freel/Aurilla at 3B, unless there's a late-signing FA out there that I'm not aware of. Maybe the Pirate's would do a Milton-for-Randa deal.
