According to Jim Salisbury of CSNPhilly.com, there is a decent amount of interest in Phillies closer Jonathan Papelbon. Salisbury mentions the Blue Jays as a possible suitor, while Ken Rosenthal of FOX Sports implied that the Cubs have had recent interest.
From Salisbury:
Papelbon’s contract remains an issue. He is owed the remainder of $13 million for this season and is just 26 games finished away from having his deal guaranteed for $13 million next season. He could make guaranteeing that $13 million up front a requirement for accepting a deal. The Phillies have long made it clear that they would eat salary to facilitate trades, provided they get value in return.
