K-Rod's deal was reworked when he was traded from the Mets during the All-Star break, changing it from an option that would have become guaranteed had he finished 55 games. Rodriguez, used as a setup man by the Brewers, gets a $4 million buyout, up from the original $3.5 million.

McLouth receives a $1.25 million buyout rather than a $10.65 million salary for next year under the contract he signed with Pittsburgh before the 2009 season.
Cook had an $11,125,000 option with a $500,000 buyout.
Harang declined his $5 million player option but does not get a $500,000 buyout because he fell 14 1/3 innings short of the 185 specified in his contract. San Diego declined a $6 million option on Qualls, who gets a $1.05 million buyout.
Hawpe gets a $1 million buyout rather than a $6 million salary.
In a deal that has not been announced, pitcher Javier Lopez agreed to an $8.5-million, two-year contract with the San Francisco Giants rather than become a free agent.

This year's free agents are headed by Albert Pujols, Prince Fielder, Jose Reyes, C.J. Wilson, Edwin Jackson and Mark Buehrle.
