According to Jim Baumbach:

Also, he hired Gregg Clifton as his new agent. If you recall, he fired Scott Shapiro as his agent a year ago and told the union he was doing so because Shapiro did not follow through on his promise to get him a four-year, $40-million deal. Pavano, of course, signed for four years and $39.95 million.

lol. It's a good thing for him that he's not signed to a contract that allows us to be that strict with him.
