The first moves were initially lateral moves. As they were tied down to slow railroad timetables, the first teams that moved stayed within Major League Baseball historical geographical core: the Northeast and upper Midwest, and to markets which did not have Major League Baseball.
The exit of the National League from Boston The first move was the Boston Braves, who moved (for 1953) to
Milwaukee, home of their top farm team, the Milwaukee Brewers. The City of Milwaukee fell in love with the Braves, with fan support of the team high, making the move highly profitable. The Milwaukee Braves would remain popular until the team moved to Atlanta in 1966.
The exit of the American League from St. Louis and Philadelphia Other owners took notice and began to issue similar threats. The St. Louis Browns moved to
Baltimore for 1954, becoming the
Baltimore Orioles (this was the era's sole west-to-east move). The Philadelphia Athletics moved to
Kansas City for 1955, briefly displacing the Cardinals as the westernmost town in the majors. Save for some controversy with the Athletics, these moves were not controversial, as these were three of the least successful teams in the majors, although the Browns and Braves had both won league championships in the 1940s.
The exit of the National League from New York City 1960s Baseball experts consider
Walter O'Malley to be "perhaps the most influential owner of baseball's early expansion era". Following the
1957 Major League Baseball season, he moved the Dodgers to Los Angeles. Frustrated, he began to look elsewhere. With the post–World War II population shifts south and west and the rise in transcontinental airplane service, many West Coast cities were actively pursuing Major League Baseball to move there; among them Los Angeles and San Francisco.
Rosalind Wyman, the then-head of the
Los Angeles Chamber of Commerce, was one of those championing a major league team in Los Angeles. Beginning in 1955, with the city's blessing, she began to solicit several major league teams, including the Dodgers, with the idea that they move to Los Angeles. Wyman and city officials attended the
1956 World Series between the Dodgers and the Yankees, at Ebbets Field, initially to meet with
Washington Senators owner
Calvin Griffith who was attending the game, to convince Griffith to move his ailing Senators to Los Angeles. O'Malley, upon hearing of the planned meeting, immediately summoned Wyman for a meeting and earnestly began negotiations with her expressing his intent to have a new modern stadium built for the team, a request Wyman and city officials assured O'Malley would be no problem. Initially O'Malley planned to use his negotiations with Los Angeles as a ploy in his dealings with New York's all-powerful public building and development czar
Robert Moses, who was preventing O'Malley from obtaining the site he was looking for in Brooklyn for his
new stadium. However, as negotiations with Moses deteriorated—Moses wanted the Dodgers to move to a new stadium site in
Flushing Meadows–Corona Park in
Queens, which eventually became
Shea Stadium—O'Malley realized that a deal with Los Angeles began to seem more of a reality. In addition, in Los Angeles, the Dodgers would be given land at
Chavez Ravine free of charge to build a stadium, which would eventually become
Dodger Stadium. O'Malley invited
San Francisco Mayor George Christopher to New York to meet with Stoneham and convinced him to join O'Malley on the West Coast at the end of the 1957 season, thus bringing the two teams' New York rivalry out to California. O'Malley needed another team to go west with him, for had he moved out west alone, the
St. Louis Cardinals— away— would have been the closest National League team. The joint move would make West Coast road trips economical for visiting teams. Since the meetings occurred during the 1957 season and against the wishes of
Commissioner of Baseball Ford Frick, there was media gamesmanship. When O'Malley moved the Dodgers from Brooklyn, the story transcended the world of sport and he found himself on the cover of
Time magazine. The
cover art for the issue was created by sports cartoonist
Willard Mullin, long noted for his caricature of the "Brooklyn Bum" that personified the team. The dual moves broke the hearts of New York's National League fans, but ultimately were successful for both franchises and for Major League Baseball. The move was an immediate success as well, because the Dodgers set a major-league, single-game attendance record in their first home appearance, with 78,672 fans at the
Los Angeles Memorial Coliseum, which would be their temporary home for several years until their new stadium was ready. New York City mayor
Robert F. Wagner asked attorney William A. Shea to head up a committee to acquire a new National League team for New York. After pitching to Philadelphia, Cincinnati, and Pittsburgh, Shea realized he was asking a team to do what he couldn't—that was move a team from a market that supported it. Almost immediately the goal was switched from moving franchises to expanding the league. Using contacts in government, he was able to force MLB (by lobbying for the end of MLB's Anti-Trust exemption) to add two American League teams and two National League teams. The
New York Mets were eventually added as an
expansion team, beginning play in 1962. Ironically, the Yankees' attendance declined slightly in the years immediately following the Dodgers' and Giants' departure, and the Mets consistently drew more fans than the Yankees through the early- to mid- 1970s. The Mets today are often considered "New York City's team" while the Yankees have a wider fanbase, similar to that of football's
Dallas Cowboys.
The Braves and Athletics move again The Braves and Athletics did not stay in their locations for very long. The Braves, despite success in Milwaukee, moved to
Atlanta for 1966 while the Athletics set up shop in
Oakland for 1968. Both markets would eventually get replacement teams: the
Milwaukee Brewers and
Kansas City Royals, respectively. The Braves would not have consistent success in Atlanta until the 1990s, while the A's were intermittently successful. ==Subsequent moves==
