Quote: Another frequent violation is of Rule 6.02 (b), which states, "The batter may not leave his position in the batter's box after the pitcher comes to Set Position, or starts his windup." In fact, the Playing Rules Committee has clarified this rule to mean that the batter cannot call "time' after this point "even though the batter claims 'dust in his eyes,' 'steamed glasses,' 'didn't get the sign' or for any other cause."

Is the rule, as well as the clarification that he wrote correct?

The writer is correct in his literal interpretation of the rule; however, he is obviously unaware of the modern custom and practice in the enforcement of the rule, and the reasons for it. Following is an explanation from Jim Evans' <i>Baseball Rules Annotated</i>:

<b>Professional Interpretation:</b> The umpire should not enforce this rule literally. Pitchers should not be able to hold the batter in abeyance for an exceptionally long period simply because he has reached his set position.
Once a pitcher starts his wind-up, time shall not be granted.

<b>Customs and Usage:</b> If a pitcher pauses unnecessarily in his set position or he starts his wind-up before the batter is reasonably set, the umpire shall call Time and play shall start over from "scratch".
If the umpire considers the batter's request for time legitimate and in the interest of safety, time generally should be granted. This is strictly umpire's judgment and no policy should be followed that would allow an advantage to either pitcher or hitter.

When was this article written? Ken Kaiser has not umpired in a few years. Eric Gregg even longer I think. He should go out and call a little league game and then he can see how easy it is. He'll realize that he will miss a lot of calls and even when he gets them right, they'll stil complain.
