UPDATE: Kovacevic now writes that one of his sources is also saying there's a deal, although the Pirates continue to say there isn't.
UPDATE: For what it's worth, Joel Sherman of the New York Post says a source tells him a deal is "definitely" going to happen.
UPDATE: Kovacevic writes that the deal isn't certain.
UPDATE: Jen Langosch reports that Sanchez won't be heading back east with the Pirates after today's game, and will instead stay in Arizona with his family in case he is traded to a team on the West Coast.
