2017 – Major League Baseball adopts a significant rule change, as part of a strategy to speed up the game: a pitcher will no longer need to throw four pitches deliberately outside the strike zone in order to issue an intentional walk, but instead the defensive team’s manager will simply need to signal his intention to the home plate umpire, who will immediately direct the batter to advance to first base. However, given that there is on average one intentional walk every 2.5 games, the change is expected to have only a minimal impact on playing time.
