The 26-year-old made his big league debut for Toronto last season and allowed five earned runs over 10 1/3 innings. He also went 2-1 with a 3.79 ERA over 35 2/3 innings for Triple-A Buffalo.
Girodo won't crack the 25-man roster, but he could still regain his standing within the organization with a strong start in Buffalo. He will be competing with Matt Dermody, Aaron Loup and Brett Oberholtzer among others to warrant consideration during the season if anything happens to Howell, who is Toronto's primary lefty reliever.
