WASHINGTON -- The Nationals requested release waivers on Mauro Gomez, who plans to play the 2014 season in Japan.

Gomez, 29, briefly joined the Nats organization late this season, but he never appeared in a game after being claimed off waivers from the Blue Jays on Sept. 5.

This past season, Gomez hit 29 home runs for Triple-A Buffalo to match Zach Walters (Triple-A Syracuse), the Nationals' No. 13-ranked prospect, for the lead among all Triple-A players.
