Well, this is interesting: http://twitter.com/FeinsandNYDN/status/400714228249550848
I don't believe this is a possibility solely because the Yankees believe they need to replace A-Rod, I think Freese it is an insurance policy. Some people seem to be jumping the gun a bit and think that it's a foregone conclusion that Rodriguez will be suspended. Freese could share third base duties with Rodriguez if the suspension is overturned or is scaled back from the 211 MLB is looking for.
Anyway, Freese could be a good pickup for the Yankees. He played in 138 games for the Cardinals last year and batted .262/.340/.381/.721. I realize it's not stellar but Jayson Nix, who played third base the most for the Yankees last season batted .236/.308/.311/.619 in 86 games.
