But doesn't Matsuzaka go back to Japan for another year if boston doesn't sign him?
It depends on MLB and Selig. It could either render the whole decision null and void, where Seibu would send the cash back and the Red Sox send Matsuzaka back across to the Lions, or...
...since the Mets placed the second-highest bid, by rights, they should get the rights to negotiate, and Seibu will still get its cash.
From what I understand, it could go either way if the deal falls through.
