Mets closer Francisco Rodriguez has hired Scott Boras to be his agent, according to a source. He was previously represented by Paul Kinzer. Rodriguez, who signed a three-year, $37 million free-agent contract prior to the 2009 season, will vest a $17.5 million contract option for 2012 if he finishes 55 games this season, a mark he is on pace to surpass. He ranks among the Mets most likely to be traded prior to this month's non-waiver deadline. An acquiring team could use Rodriguez as a setup man, thereby avoiding his option.
