Woah.
Supposedly a reason the terms were so agreeable was that the Sox agreed to give a chance for Sale to join the bullpen this year. Chris will report to W-S with hopes of being promoted to Charlotte by July and to Chicago in August. He will than return to starting in the AFL with a chance to break camp with the Sox next year as a SP.
