According to Jane Lee of MLB.com, Scott Sizemore is fully healthy after missing the entire 2012 season with a torn ACL in his left knee. Sizemore was scheduled to be the A's starting third baseman for the 2012 season before the injury on this first day of workouts derailed his season. He'll head into spring training competing for time at both third and second base. He has an intriguing blend of power and speed, and could be a potential fantasy sleeper if he can find his way into an everyday role.
