San Diego Padres superstar Fernando Tatis Jr. is suing Big League Advance Fund and owes the company millions of dollars.

BLA and similar companies have been accused of predatory tactics and locking young minor-leaguers, often Latin American players from poor backgrounds, into agreements they don't fully understand. Former major league catcher Francisco Mejía is among several others suing BLA.

San Diego Padres star Fernando Tatis Jr. filed a lawsuit on Monday against Big League Advance (BLA), attempting to void a contract he signed as a teenage minor-leaguer that states he owes the company a share of his future earnings.
