The Nationals have released southpaw reliever Michael Gonzalez, tweets Adam Kilgore of the Washington Post. Gonzalez had a Thursday opt-out date, notes Mark Zuckerman of CSNwashington.com (on Twitter).
The 35-year-old seemed a long shot for a slot after the club decided to add Ross Detwiler to the pen. He joined the Nats just three weeks ago after spending 2013 with the Brewers. Gonzalez was an important part of the Nationals club down the stretch in 2012, after signing mid-season.
