Rob Biertempfel writes that Pirates reliever Brad Lincoln could be a part of trade talks for Diamondbacks outfielder Justin Upton or Padres outfielder Carlos Quentin.

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.

Lincoln would, of course, be a complementary player in an Upton trade, but not a main piece. He shows signs of being an excellent reliever, but has struggled as a starter.

The Diamondbacks sending a scout to Indianapolis could be a sign that they are interested in outfielder Starling Marte, one of the Pirates' better prospects and a potential key to acquiring a player of Upton's quality.

The West Virginia roster includes a number of interesting players. Infielder Alen Hanson would be too much to give up for Quentin, who is eligible for free agency after the season, but there are also outfielders Gregory Polanco and Willy Garcia, and others.
