Pirates pitcher Harvey Haddix. The 1961 season saw a drop in the standings for the Braves down to fourth, despite Spahn recording his 300th victory and pitching another no-hitter that year. Aaron hit 45 home runs in 1962, a Milwaukee career high for him, but this did not translate into wins for the Braves, as they finished fifth. The next season, Aaron again hit 44 home runs and notched 130 RBI, and 42-year-old Warren Spahn was once again the ace of the staff, going 23–7. However, none of the other Braves produced at that level, and the team finished in the "second division", for the first time in its short history in Milwaukee. The Braves were mediocre as the 1960s began, with an inflated win total fed by the expansion New York Mets and Houston Colt .45s. To this day, the Milwaukee Braves are the only major league team that played more than one season and never had a losing record. Perini sold the Braves to a Chicago-based group led by William Bartholomay in 1962. Almost immediately Bartholomay started shopping the Braves to a larger television market. Keen to attract them, the fast-growing city of Atlanta, led by Mayor Ivan Allen Jr. constructed a new $18 million, 52,000-seat ballpark in less than one year, Atlanta Stadium, which was officially opened in 1965 in hopes of luring an existing major league baseball and/or NFL/AFL team. After the city failed to lure the Kansas City A's to Atlanta (the A's ultimately moved to Oakland in 1968), the Braves announced their intention to move to Atlanta for the 1965 season. However, an injunction filed in Wisconsin kept the Braves in Milwaukee for one final year. In 1966, the Braves completed the move to Atlanta. Eddie Mathews is the only Braves player to have played for the organization in all three cities that they have been based in. Mathews played with the Braves for their last season in Boston, the team's entire tenure in Milwaukee, and their first season in Atlanta. Atlanta (1966–present) 1966–1974 The Braves were a .500 team in their first few years in Atlanta; 85–77 in 1966, 77–85 in 1967, and 81–81 in 1968. The 1967 season was the Braves' first losing season since 1952, their last year in Boston. In 1969, with the onset of divisional play, the Braves won the first-ever National League West Division title, before being swept
