San Diego Padres star Fernando Tatis Jr. is suing Big League Advance in an attempt to void the future earnings contract he signed as a 17-year-old minor leaguer that could cost him about $34 million. The lawsuit, filed in San Diego County Superior Court, accuses BLA of using predatory tactics to lure him into an “investment deal” that was actually an illegal loan. The suit alleges BLA misrepresented itself to Tatis, hiding its unlicensed status and pushing him into loan terms banned by California’s consumer protection laws. Attorney Robert Hertzberg said the suit also seeks public injunctive relief to protect young athletes from such deals.
