Step 1: Throw strike. Out of fear, the batter will not swing.
Step 2: Throw a slightly different, more tempting but impossible to hit strike. Foolishly, the batter will swing as if he thinks he could make contact.
Step 3: Buckle the batters knees by issuing a strike with the precision of a surgeons laser. The batter will turn and shake his head, knowingly, as he retreats to the dugout in shame.
Repeat as necessary.
