History of Baseball's Antitrust Exemption

Skip over at the Sports Economist points to a great article detailing the history of baseball's antitrust exemption (Ratner, "Orioles run-ins with law historic," Baltimore Sun, 4/3/05). Skip also helpfully points out one error the author makes, relating to franchise location. I have done some analysis of the decision in Federal League Baseball Club of Baltimore v. National League, which created the exemption, in this earlier post (12/8/04).
