Mitch Stetter has been cleared to throw Friday after missing the last three and a half weeks with a bulging disc in his lower back.
Assuming he doesn't have any setbacks, the injury shouldn't hurt his chances at winning an Opening Day bullpen spot. Stetter is in camp as a non-roster invitee after posting a 2.67 ERA while striking out 40 over 30 1/3 innings between Double- and Triple-A in 2012.
