I recently got into a discussion with some coaches about balks and thought I would share the following:
Eleven ways to balk
1) Make a quick pitch.
This seems to be the most common balk called at any level. The pitcher must come to a complete stop from the set position and must not pitch before the batter is ready.
2) Pitch while not touching the rubber.
The post foot must be in contact with the rubber while beginning the delivery. (As soon as the pitcher goes into foot-strike the post foot will naturally drag forward toward home plate and will not touch the rubber as the torso rotates). The consistent bend of the post leg from start to finish proves the concept of "pushing off" the rubber is nothing but a popular myth.
3) Fake the pitch.
The pitcher can't make any movement to deceive the runner or batter.
4) Fail to have both hands on the baseball in the set position.
5) Pitch without looking at the batter.
6) Fake a throw to first base.
7) Make a pitching motion without completing the pitch.
8) Drop the baseball while on the rubber.
9) Delay the game.
10) If the catcher is out of the catcher's box during an intentional walk.
11) Fail to step toward and ahead of the throw.
This makes any type of "spin-move" illegal.
