The Nationals announced that they have signed lefty Mike Gonzalez to a minor league deal with an invitation to Major League Spring Training (Twitter link). Gonzalez is represented by the MVP Sports Group.

Usually one to hold lefties in check, the 35-year-old Gonzalez struggled in that regard last season, surrendering a .274/.336/.443 batting line to opposing lefties en route to a 4.68 ERA in 50 innings with the Brewers. However, his career mark of .219/.287/.346 is a significant improvement from last year's split, and he's just one season removed from posting a 3.03 ERA with 9.8 K/9 and 4.0 BB/9 in 2012 -- a season he spent with the Nationals.

Washington has a crowded bullpen mix with Rafael Soriano, Drew Storen, Tyler Clippard, Jerry Blevins, Ross Ohlendorf and Craig Stammen each already set to earn north of the Major League minimum.
