The Phillies want "the world" for pitcher Cole Hamels, according to CBSSports.com Baseball Insider Jon Heyman.

The club is willing to trade Hamels, but only if there's a big return. Hamels can block trades to 20 clubs, but could be willing to waive his no-trade clause based on the Phillies poor performance. Hamels is still owed $105 million on his deal, which could limit the teams that can actually make a play for the left-hander. 

Over 122 1/3 innings, Hamels has a 2.72 ERA.
