The Phillies' rebuilding program really won't commence until they deal their most valuable asset, left-handed starting pitcher Cole Hamels, who is also the most valuable player on the trade market right now.
The Phillies probably will have to wait until free agents Max Scherzer and Jon Lester have found new homes before they find the right trade partner, but that won't stop Phillies GM Ruben Amaro from laying the groundwork between now and then. Hamels, 30, is one of the best left-handed pitchers in baseball and is coming off another sensational year (6.6 WAR, 2.46 ERA, 3.07 FIP and 1.15 WHIP in 30 starts). His contract is also club-friendly, with four years remaining at a fair market value of $22.5 million per season.
One of the problems the Phillies have to deal with, however, is Hamels has 20 teams on his no-trade list, which leaves just nine teams. He might be willing to waive it for certain clubs, especially if they agree to pick up his option year or if he is given some type of assignment bonus, but the Phillies also have a limited market of teams that both can afford to take on Hamels' contract and have the top prospects to send back in this magnitude of a deal.
Although there are other possibilities, the Cubs, Cardinals, Dodgers and Red Sox are probably the four teams that match up the best with the Phillies.
