In addition to $ 275 million over ten years, Alex Rodriguez also stands to earn some pretty healthy incentives for reaching home run milestones:
NEW YORK (AP) — Alex Rodriguez and the New York Yankees have agreed on a $30 million marketing package based on home-run achievements that could raise the total value of his new contract to $305 million over 10 years.
Under the agreement, which remains to be finalized, Rodriguez could receive $6 million each for tying the home-run levels of Willie Mays (660), Babe Ruth (714), Hank Aaron (755) and Barry Bonds (762), and an additional $6 million for breaking Bonds’ major league record.
The Yankees could designate each level as a historic event, enabling Rodriguez to receive the added money in exchange for additional personal appearances and signed memorabilia for the club. That enabled the agreement to be allowed by the players’ association and the commissioner’s office. Baseball generally prohibits bonuses based on statistics such as home runs.
And you can expect the Yankees to promote the hell out of this over the next ten years or so.
