The Yankee is playing hardball in his divorce!

Yankee all-star Alex Rodriguez isn't backing down without a fight in his divorce case! In papers that will be filed today in Miami, A-Rod wants his prenup enforced and allegations of "extramarital affairs and other misconduct" removed from the record.

Rodriguez believes his marriage to estranged wife Cynthia is "irretrievably broken," but due to Florida being a no-fault divorce state, there does not have to be an explanation.

If A-Rod has to go to court to fight a challenge to the prenup and wins, he plans to recover from his wife any "reasonable attorney's fees and costs." 

According to papers, this will not effect his two daughters. The baseball star has "been paying, and will continue to pay...reasonable and bona fide expenses" for the girls.

The New York Daily News reports, documents should be filed today in the Miami-Dade Court in Florida.

A-Rod's attorney Alan Kluger spoke out to "The Insider" saying, "They're both going through difficult times. Neither they, nor their lawyers, want to try this case in the press. Papers that both parties filed will be the best expressions of their positions."
