Looks like Kei Igawa was pushed off the Yankee's 40-man roster after the team acquired Damaso Marte and Xavier Nady. He cleared waivers unclaimed.
Nikkan Sports has a quote from Igawa:
"I was told by my agent that this increases my chance of playing for a different team. I have absolutely no interest in going back to Japan. I want to deal with this in the minors and seize my opportunity to reach the Majors in America."
I hope the Yankees do find a way to move Igawa to a different team. It seems clear that he'll never thrive in NYC, but if he had a chance to move to an NL team in a good pitcher's park, he might do alright.
