I'd think the California teams and any World Series contender would pretty much sum it up, though depending on how serious he is about getting out it could be longer...
I don't see any of the California teams being in play, well if Young wants his request to be granted and play SS.
Dodgers - Just signed Rafael Furcal to a 3 year deal.
Giants - Just signed Edgar Renteria to a 2 year deal.
Padres - traded away Khalil Greene, but unless the Rangers pick up the tab, the Fathers are not picking up anybody.
Angels - I don't think the Rangers would deal him within the division.
A's - See Angels.
The majority of that roster will be on the DL by July,
