The Philadelphia Phillies have increased their efforts to trade away Jonathan Papelbon in recent days, according to sources.

There have been no indications that a deal is imminent.

The Phillies have called a number of contenders with potential need for a closer and told them the club would be willing to eat a portion of Papelbon's $13 million salary for this year, along with a portion of his $13 million vesting option for next season, according to source.
