Girodo was outrighted to Triple-A Buffalo on Wednesday, Ben Nicholson-Smith of Sportsnet.ca reports.
The southpaw will remain with the organization after being removed from the 40-man roster. He will still get to attend major league camp for spring training, but Girodo will face long odds to earn his spot back with lefties J.P. Howell, Aaron Loup and Matt Dermody all ahead of him in the bullpen hierarchy.
