Early in 1957 came rumors that the Dodgers might leave Brooklyn for Los Angeles. Walter O'Malley started to talk to Horace Stoneham, owner of the Giants, about joining him in a move west, arguing that the other National League owners, mindful of their travel expenses, would not approve the move of a single team so far away from the others. Stoneham, who had been eyeing a move to Minneapolis, did not need much convincing. The Giants' board of directors voted to move on August 19, 1957; the Dodgers' board followed suit on October 8.
