A-Rod: Marriage "Broken," But Prenup Sound

Yankee star says there's no salvaging union but makes no mention of Madonna or affairs

Alex Rodriguez is trying to go down without much of his fight. (No, we're not referring to his postseason play.)

In court documents filed Thursday, the Yankees slugger admits to much of what was set forth by estranged wife Cynthia Rodriguez in the divorce petition she filed earlier this month, including her characterization of their five-year marriage as "irretrievably broken" (he makes mention in court docs of a certain Material acquaintance or any dalliances) and that Cynthia is a "loving and nurturing mother."

Notably, he denied her challenge of their prenuptial agreement, drawn up once upon a time to protect baseball's highest paid player from potentially coffer-draining situations such as this one.

Rodriguez, while agreeing to pay for their daughters' needs, also "denies any duty to support Wife beyond those obligations" specifically laid out in the prenup.

His camp maintains that Cynthia Rodriguez was free to consult her own attorney before signing the agreement "freely and voluntarily" and after seeing a complete accounting of A-Rod's financials.

Rodriguez also requests that he and Cynthia be named "co-residential" parents due to his heavy traveling schedule. He wants joint custody but acknowledges that their children will end up spending more face-to-face time with their mom, especially while he's on the road during baseball season.
