the New York Giants, moved to the Mexican League. These moves were motivated by businessman Jorge Pasquel investing more money to raise the profile of the Mexican League and offering contracts which were in some cases higher than American Major League contracts. These moves were also motivated by the anticipation of increased competition from former Major Leaguers who had been serving in World War II and were now returning home. 1949: Landmark ruling of Gardella v. Chandler The U.S. Supreme Court case Federal Baseball Club of Baltimore v. National League of Professional Baseball Clubs held that the baseball leagues and their commissioner are not violating antitrust laws (specifically the Sherman Antitrust Act) when they ban, trade, or otherwise change the playing eligibility of players. The ruling went untested until the Mexican League was formed. Players who went to play in the Mexican League were blacklisted from Major League Baseball. One such player, Danny Gardella, was blacklisted because MLB claimed he had violated the reserve clause. On the other hand, Gardella's side claimed he had been fired by Giants player-manager Mel Ott during 1946 spring training because of frequent arguments, primarily about his salary. During 1948, Gardella brought a claim against Commissioner of Baseball Happy Chandler, the National League and American League, as well as their presidents (Ford Frick and Will Harridge, respectively). Gardella charged that they were engaged in interstate commerce because the defendants had made contracts with radio broadcasting and television companies that sent narratives or moving pictures of the games across state lines. MLB then settled with Gardella and offered all Mexican League jumpers amnesty, protecting the ambiguity of the antitrust protection. In 1949, Gardella won a major appeal against baseball's reserve clause in the federal courts. This successful appeal is recognized as the first major early step towards baseball free agency. Expansion and MiLB For most of its existence, the league consisted of six to eight teams. During its first few decades most of the league's teams played around Mexico City and the Gulf Coast. The southernmost team being Veracruz, while the northernmost team being Tampico. Most of Mexico City's teams disappeared in the late '30s, and were replaced by teams all around the country. It wasn't until the 1940s, that the League first reached the northern part of the country with the introduction of the Sultanes de Monterrey. Teams in Nuevo Laredo and Torreon soon followed.
