The Nationals and Twins have reportedly discussed a trade involving center fielder Denard Span, according to Ken Rosenthal of FoxSports.com. Span, the Twins outfielder has been out since June 7 with a concussion, but is currently on a rehab assignment.

Closer Drew Storen and All-Star setup man Tyler Clippard are players the Twins will most likely seek, but according to Rosenthal’s sources the Nationals are unwilling to deal them. Rosenthal adds that the Twins might seek right-hander’s Todd Coffey or Henry Rodriguez.

Before suffering the concussion Span was hitting .294 with two home runs and 15 RBIs. Rosenthal also notes that the Nationals are reportedly interested in outfielders including the Rays’ B.J. Upton, the Cardinals’ Colby Rasmus and the Astros’ Michael Bourn.
