I think that batters should be put on the clock. After the ball enters the catchers glove, the batter should have 20 seconds to scratch their nuts, adjust their gloves, spit, and stretch, and if they are not ready to bat at that point then a strike is called. The same thing with the pitchers. Once the batter is in the box, the pitcher has 20 seconds to make the pitch, or a ball is called.
