Ichiro in Pinstripes: The Danny Farquhar Story?

I entered the movie theater yesterday (BATMAN!!!!) assuming the Yankees were still looking for pitchers before the trade deadline. I came out of the theater with my cell phone blowing up with friends texting me about the Yankees big move. I assumed it was Cole Hamels or Zack Greinke. It was not until I opened my computer and saw the ESPN headline; Ichiro is going to be in pinstripes. The Yankees get Suzuki while the Mariners get two pitching prospects. What is the rationale of the deal? Implications for the Yankees playoff push? Is this a good deal for either team?  After the jump, I delve into those questions from the perspective of both teams.
