Many believe that Josh Hamilton and Cole Hamels will re-sign with the Rangers and Phillies, respectively, making Giants right-hander Matt Cain the prize of the 2012 free-agent class. Tim Lincecum will hit the market after the 2013 season and San Francisco could struggle to retain both pitchers. One scout listed Cain's changeup as perhaps the best in baseball this past season -- "it's one of the best right-handed I've seen this year."
