 Because I would argue about 95% of the time that's all they're doing is deceiving the runner with the pickup of the leg and dangling it there. Are they going home? Are they going to first? Two balls and two strikes to count on wisely. 1-0 Giants, bottom of the second inning. Missed downstairs with a changeup. The rule on a left-hander is if he lifts the leg up and the ankle or the foot goes past...
