The Nationals are listening on top relievers Drew Storen and Tyler Clippard, reports Ken Rosenthal of FOX Sports, but such a trade would have to fill a specific long-term need such as center field. Teams are calling on Storen, Clippard, and Todd Coffey.
Potential center field targets for Washington include B.J. Upton, Michael Bourn, Colby Rasmus, and Denard Span, writes Rosenthal. He believes that a reliever alone probably would not bring back a center fielder, but the Nats could also trade shortstop Ian Desmond since some club officials would like to move Danny Espinosa to shortstop.
Storen is under team control through 2016, Clippard and Desmond through '15. Desmond would be an interesting name for teams seeking shortstop help, though he's limped to a .226/.269/.311 line in 361 plate appearances this year.
The Nationals also have starting pitching to spare, as ESPN's Jerry Crasnick tweets that they will move Jason Marquis, Livan Hernandez, and Tom Gorzelanny. Gorzelanny is a bit of a surprise, as he's got strong strikeout and walk rates and is under team control through 2013.
