Cole Hamels’ agent, John Boggs, told Jim Salisbury of CSNPhilly.com he expects to visit with team officials in Florida at some point during spring training.

Boggs stated he would give the Phillies "every opportunity" to sign Hamels to a long-term deal. Still, it would be surprising if Hamels doesn't test the free agent market, as he'll likely command a salary in the range of $20 million per season.
It will be interesting to see if the Phillies have the money to get something done this season.  Losing Hamels would be a monumental blunder by the Phillies who have spent a ton of money of pitching.  If Hamels were to get a $20 million per season deal, he would be the fourth Phillies player with a annual deal worth that amount.
