Oliver Perez Met deal done by Saturday?

Mack of Mack's Mets had this to say about OP's pending contract situation.

BTW, who is Mack and why does he matter? MLB Hub fills in the blanks on Mack's background; Mack brings years of experience as a beat writer especially with the minor leaguers, inside scoop and a unique perspective to his site.

Mack states, "sources tell me the deal will be done by Saturday night, Sunday the latest. 4 years + a 5th year team option. No amount of monies have been disclosed as of yet."

OMG...Four years with a fifth year team option is CRAZY! I'm hoping Mack's sources were off by a year or two.
