From the New York Daily News:

The biggest buzz among the few general managers attending the World Series is the silent auction the Yankees have apparently already begun for Gary Sheffield. It turns out that Yankee GM Brian Cashman had always intended to pick up Sheffield's $13 million option for next year - but not for the purposes of keeping him. Once the Yankees acquired Bobby Abreu from the Phillies at last July's trading deadline, it was clear Sheffield no longer fit in their plans, but by picking up his option, they can now get something for him. And it could be a nice return as at least a half-dozen teams - the Angels, Orioles, Cubs, Giants, Astros and Rangers - are in the market for a power-hitting corner outfielder, and that doesn't include the Red Sox and Mets. The Yankees can now prevent Sheffield going to such rivals, not a possibility had they let him flee.

Of course, reports like this can only hurt our chances of getting anything decent for him, if Sheffield's response is to say he won't play for the team he's dealt to. But, maybe they are already taking that into account.
