CHICAGO -- Along with 20 or so other teams, the Red Sox will be in attendance Friday when former San Francisco Giants righthander Tim Lincecum throws in Scottsdale, Az. in a showcase for scouts and talent evaluators.

Indications are, however, that the Sox are merely doing their due diligence in attending the workout. It's unclear how highly they regard the 31-year-old pitcher, or what role they would envision for him.

Lincecum was a free agent last winter, but attracted little attention and spent most of the winter and early spring refining his mechanics, gearing toward this week's showcase.

Lincecum was the National League Cy Young Award winner in 2008 and 2009 and an All-Star in 2010 and 2011, but from 2012 through last year, his performance dipped considerably, with a won-loss record of 39-42 and an ERA of 4.68.

He pitched out of the bullpen some in 2014 and last season was limited to just 15 starts.

The Sox are waiting on Eduardo Rodriguez and Joe Kelly to return from injuries and have Henry Owens in the rotation currently. Additionally, Brian Johnson and Roenis Elias are depth options in Pawtucket.
