Edwin Jackson has multiple three year-offers, according to Ken Rosenthal. Jackson has had offers from both the Red Sox and the Orioles, though we haven't seen if they're the three-year variety.

  Hamels, Greinke likely at top of 2012-13 FA class if #SFGiants extend Cain. Jackson, 28, could further enhance value with strong year.
