The Braves announced the contract Friday. It includes an invitation to spring training.
The 29-year-old Young led the National League with 46 stolen bases in 2013 for Colorado and the New York Mets. He stole 30 last year with the Mets while batting .229 in 100 games.
Young is a career .252 hitter since making his big league debut in 2009 with the Rockies.
The Braves also said minor league hitting coordinator Ronnie Ortegano had resigned for personal reasons.
