All Elijah. All the Time.

The Rays site has this

Troubled Rays outfielder Elijah Dukes has been traded to the Nationals for a Minor League player, according to a source close to the Rays.
The unknown player has not yet been notified, which has delayed the deal being announced.

Ken Rosenthal has this conjecture

The identity of the minor-league player is not yet known, but he is not believed to be on the 40-man roster.

I do not believe it is going to be a top 30 guys not on the roster (no Marrero or any of the Vermonster arms). I am thinking names like Clint Everts or Larry Broadway.

More to follow.

A request was made for a scouting report on Dukes. With credit and thanks to Baseball America from 2005

Strengths:  Dukes is an incredible athlete with all-star ability. He makes solid contact, has at least 20-homer power and plays with all-out aggression. He has plus speed and range, as well as one of the strongest arms in the organization. He has demonstrated improved control of the strike zone.

Weaknesses: If he can’t accept authority and develop discipline, Dukes will fall short of his potential. That said, he’s dedicated to the game. His average suffers when he tries too hard to hit for power.

The Future: From a tools standpoint, everything is in place for Dukes to be a prototype right fielder. The Devil Rays are working with him to help him reach that potential. On the field, Delmon Young will be a formidable roadblock to Dukes playing right field in Tampa Bay.
