Two big changes are coming to major league baseball. They are 1) raising the bottom part of the strike zone and 2) no longer requiring a pitcher to throw 4 pitches out of the strike zone to issue an intentional walk - they will simply indicate to the ump that they wish to intentionally walk a batter and then the ump tells the batter to take his base.
