Cuban baseball players paid a South Florida-based smuggling ring more than $15 million to leave the communist island in secretive ventures that included phony documents, false identities and surreptitious boat voyages to Mexico, Haiti and the Dominican Republic, federal prosecutors say.

A recently unsealed grand jury indictment against three men provides fresh details about the smuggling of 17 Cuban players, among them Jose Abreu of the Chicago White Sox and Leonys Martin of the Seattle Mariners. The smugglers usually took a percentage of any Major League Baseball contract a player signed.
