The New York Yankees are putting together legal arguments to keep Alex Rodriguez from collecting any of the bonuses he is owed per the $30 million "milestone home run" agreement he signed in 2007, according sources.

If Rodriguez hits six more homers, which would tie him with Willie Mays for fourth all time, he will be eligible for a $6 million bonus under his 10-year, $275 million contract. He has hit 654 home runs in his career.

The Yankees plan on contesting the validity of the marketing deal because of Rodriguez's steroids revelations and yearlong suspension, according to a source.

Rodriguez, along with the Major League Baseball Players Association, would have the right to file a grievance.

The 38-year-old would also pocket $6 million apiece if he tied Babe Ruth (714 homers), Hank Aaron (755), Barry Bonds (762) and for surpassing Bonds.
