Why MLB Plays 162 Games

MLB played 154 game seasons for decades before moving to 162 when the leagues expanded, starting with the American League in 1961 and the National League in 1962. The longer schedule kept the balance of games between teams as more clubs joined. Baseball can play far more games than football or basketball because the sport is less physically punishing day to day, and teams use five man rotations so starting pitchers rest between outings.
