Starlin Castro has funds seized

Starlin Castro has filed a countersuit, according to a source, after reportedly having $3.6 million seized from his bank accounts after the Chicago Cubs shortstop refused to pay three percent of his earnings to a Dominican Republic baseball school.

According to multiple media reports, Castro's father, Diogenis Castro, signed an agreement with Mi Futuro Biliguer (My Future Big Leaguer) and coach Manuel Nunez when Castro was 15, requiring him to pay a percentage of his career earnings if he made the major leagues.

The source told Jesse Rogers of ESPNChicago.com that the countersuit filed by Castro's attorney discredits that contract and that a father cannot sign away a son's future earnings.

Castro paid Nunez an unspecified amount after signing his first big-league contract, but Nunez believes he is owed future earnings ,and funds were seized from several banks, according to reports.

A two-time All-Star, Castro, 23, signed a seven-year, $60 million contract with the Cubs in 2012.
