A California-based sports agent was arrested Tuesday, charged in federal court in Miami with financing and organizing a scheme to smuggle Cuban baseball players from the communist island to the United States. Baseball agent Gustavo ''Gus'' Dominguez of Total Sports International is accused of hiring four men to help him get 19 Cubans off the island on Aug. 22, 2004, including several who are now U.S. minor-league baseball players. The voyage also included three children only identified by their initials. Dominguez's Beverly Hills company represents some 50 players, including pitcher Jason Simontacchi, former Marlin Greg Colbrunn and Cuban defectors Eddy Oropesa and Andy Morales. Dominguez has said he represents 38 Cuban defectors.
