If a deal is made by Thursday, my sense is it involves closer George Sherrill. General managers love this guy for his no-fear attitude (we saw that again Tuesday) and his versatility. He can close, setup or get out the tough lefty. He's perfect for a contender. And he isn't arbitration-eligible yet, so he'll be under a club's control through 2011. He'll be 34 by then, so he's not really a good fit for a rebuilding team. And his value probably will never be higher, coming off a strong first half and an outstanding All-Star game performance and heading into a market chock full of contenders with bullpen issues.
