The Seattle Pilots were an American professional baseball team based in Seattle. Based at Sick's Stadium, the team played for just one season, 1969, finishing last in the West Division of Major League Baseball's American League with a 64–98 record. On April 1, 1970, the franchise moved to Milwaukee, Wisconsin, and became the Milwaukee Brewers. After the move, Seattle and King County sued the American League, which consequently granted the city a new expansion franchise, the Seattle Mariners.
