The Nationals announced that they have signed left-handed reliever Mike Gonzalez (Twitter link). Gonzalez, a client of the Boras Corporation, will report to Viera, the team announced. He signed a minor league deal, Adam Kilgore of the Washington Post tweets.

Gonzalez posted a 4.39 ERA with 8.6 K/9 and 3.5 BB/9 in 53 1/3 innings for the Orioles and Rangers in 2011. The Indians, White Sox and Athletics had some interest in the 33-year-old, who turned down a minor league offer from the Rangers this spring. Scott Boras has said Gonzalez is returning to health following offseason knee surgery.

The Nationals' bullpen currently includes left-handers Sean Burnett and Tom Gorzelanny. As MLBTR's Agency Database shows, the Boras Corporation represents a considerable number of players on Washington's roster.
