David Roberston is looking for "Papelbon money" in talks with teams, according to a source.

The Philadelphia Phillies signed Jonathan Papelbon to a four-year, $50 million deal in 2011, the richest overall contract for a reliever.

If Papelbon finishes 15 games in 2015, his contract will vest for a fifth year at $13 million more, making it a total of five years and $63 million.

If Robertson and his agent, Scott Leventhal, can persuade one team to offer "Papelbon money," it is doubtful the New York Yankees would match.
