Mike Gonzalez was spotted throwing a bullpen session during an audition for the Reds at their Spring Training complex on Monday, reports Mark Sheldon of MLB.com. With Sean Marshall set to close following Ryan Madson's injury, Cincinnati could be looking to add a left-handed setup man.

Gonzalez, 33, remains a free agent despite recent interest from the Red Sox, Indians, White Sox, and Rangers. The lefty reliever had knee surgery early in the offseason and appears unwilling to sign a minor league contract at the moment.
