The late 1960s and 70s were a tumultuous time for the Sox, as they struggled to win games and attract fans. Allyn and Bud Selig agreed to a handshake deal that would give Selig control of the club and move them to Milwaukee; however, this was blocked by the American League. Selig instead bought the Seattle Pilots and moved them to Milwaukee, putting enormous pressure on the American League to place a team in Seattle. A plan was in place for the Sox to move to Seattle and for Charlie Finley to move his Oakland A's to Chicago. However, Chicago had a renewed interest in the Sox after the 1972 season, and the American League instead added the expansion Seattle Mariners. The 1972 White Sox had the lone successful season of this era, as Dick Allen wound up winning the American League MVP award. Some[who?] have said that Dick Allen is responsible for saving the White Sox in Chicago. Bill Veeck returned as owner of the Sox in 1975, and despite not having much money, they managed to win 90 games in 1977, a team known as the South Side Hitmen.
