Windup Balk

[GarthB]

Also remember for any balk the intent of the rule is to prevent pitchers attempting to decieve runners.

Not completely true. Some deception is legal e.g.varying the set point and changing tempo.

While most balks are called for illegally deceiving the runner(s) the rules include some balks that are based on mechanical issues and violation of the prescribed
"behavior" of a pitcher rather than deception.

An example of a mechanical balk would be 8.05 (e)"The pitcher makes an illegal pitch;"

This references OBR 8.01(d): “If the pitcher makes an illegal pitch with the bases unoccupied, it shall be called a ball…”

Of course, we all know that an illegal pitch is one in which the pitcher delivers the ball before the batter is reasonably set (quick pitch), or when the pitcher is not in contact with the rubber. (Right?)

An example of a penal balk would be 8.05 (h)"The pitcher unnecessarily delays the game;"
