Detroit Tigers slugger Miguel Cabrera is being sued by a Florida woman who says the two-time Most Valuable Player isn’t paying enough to support two children he fathered with her, setting up a legal showdown that could cost the superstar more than $100,000 a month.

The allegations are contained in court records obtained by The Detroit News that chronicle a public fight over money and offer insight into the personal life of a married, intensely private, baseball player who has three children with his wife of 15 years, Rosangel.

Belkis Mariela Rodriguez, 35, of Orlando, sued Cabrera in Florida in August after the Tigers first baseman allegedly slashed child-support payments, a move that coincided with the Tigers veteran helping her buy a nearly $1 million home earlier this year. Cabrera is one of the world’s wealthiest athletes, earning more than $30 million a year, but is fighting over how much money the children should receive.

Cabrera, 34, wants paternity tests conducted on the children, born in 2013 and 2015, and has accused Rodriguez of extorting him, according to court records. It’s unclear if those tests have been administered. Cabrera currently is paying her more than $6,200 a month.
