SAN FRANCISCO (AP) — A federal judge dismissed an antitrust lawsuit filed by minor league players against Major League Baseball and its 30 teams. U.S. District Judge Haywood S. Gilliam Jr. ruled Monday the defendants are protected from the legal challenge by the sport’s antitrust exemption, created by the Supreme Court in 1922. Four former players, Sergio Miranda, Jeffrey Dominguez, Jorge Padilla and Cirilo Cruz, alleged MLB’s reserve clause illegally restricts them to one major league organization exclusively for up to seven years.
