The Nationals and Athletics continued their prolific recent trading history with a minor deal that sent outfielder Corey Brown back to Oakland for “cash considerations” three years after the Nationals acquired him.

The Nationals designated Brown for assignment last week in order to make room on their roster for newly signed outfielder Nate McLouth. Brown has no minor league options remaining, which meant the Nationals would have needed to carry Brown on their active roster to not risk losing him on waivers.

Brown, 28, came to the Nationals in December 2010 along with reliever Henry Rodriguez in the the trade that sent Josh Willingham to Oakland. Circumstances and injuries prevented Brown from establishing himself at the major league level with the Nationals. Over three seasons, Brown appeared in 36 major league games and got 40 at-bats, recording seven hits and a homer.

Still, Brown may well make the A’s roster. He has the speed to play all three outfield spots. Last season at Class AAA Syracuse, Brown hit .254/.326/.473 with 19 homers. In 2012 at Syracuse, Brown hit 25 homers in 126 games with a .365 on-base percentage.

The Nationals and A’s had already made two trades this winter. Washington sent reliever Fernando Abad – who also had been designated for assignment – to Oakland for Class A outfielder John Wooten. Last week at the winter meetings, the Nationals acquired reliever Jerry Blevins for Class AA outfielder Billy Burns.
