Lore & Background

The Athletics moved to Oakland from Kansas City in 1968, where the team had previously relocated in 1954 from its original home in Philadelphia. The Athletics were successful in Oakland, winning four World Series championships, six American League pennants, and 17 Western Division titles. Despite the team's accomplishments, the Athletics left Oakland after the 2024 season, citing the aging Oakland Coliseum and inability to secure taxpayer funding for a new ballpark in the East Bay or San Jose areas. In 2025, the team relocated to West Sacramento as the Athletics, with an eventual planned relocation to the Las Vegas metropolitan area on a permanent basis. The move marked the end of professional major league sports in Oakland.
