I think the yankees lure on Igawa was his age and that fact that he is a lefty. In 2 yrs, Johnson, Pettitte, and Mussina will be history. Wang will still be in NY god willing, Hughes, and Sanchez may be in the rotation, Clippard possibly, maybe Joba, who knows. Maybe Zambrano or Sheets or whomever. But a left handed pitcher of that age is hard to come by and since the yankees have no interest in Zito, it works for them to have a young lefty who could be a durable back end of the rotation guy. Now, no other team could harbor him in AAA after the posting fee, but that is why it is good to be a yankee.
