I've heard D'backs and Padres might have some degree of interest in #Pirates RHP Brad Lincoln as part of deals for Upton/Quentin. Dbacks offered Upton to Pirates and have sent scout to Triple-A Indy to start compiling wish list. Padres sent scout to Low-A West Virginia.
Obviously, Lincoln wouldn't be a key piece in an Upton deal. The Diamondbacks scouting Indianapolis might mean they're interested in Starling Marte, who's really the only big-time prospect there.
As for West Virginia, Alen Hanson is too much to give up for a rent-a-player like Quentin, so I'd expect players like Willy Garcia, Nick Kingham and perhaps Gregory Polanco could be in play. But who knows. I would think that the Pirates would be pretty reluctant to give up a toolsy player like Polanco for a rental, even a good one like Quentin. Pure speculation here, obviously -- I'm just trying to guess what the Padres might be thinking.
