The "look back" rule is one of those rules that is irrelevant to well-trained teams. It is a non-issue. The only teams that have problems with the look back rule are poorly trained.
The proper way to defend teams taking advantage of the look back rule:
(1) the pitcher takes the throw back from the catcher already in a position to throw the ball. The pitcher is sideways, facing either 1B or 3B, depending upon the situation. After receiving the ball, the pitcher walks back to the mound keeping an eye on the runner until the runner returns to the bag.
(2) The defenders are covering the bags, with the outfielders in appropriate back up positions.
(3) If the runner is too far off the bag, the pitcher jogs *AT THE RUNNER* showing the ball to the fielders at the bases on opposite sides of the runner. She continues running toward the runner until the runner commits to one base or the other, at which time the pitcher throws the ball to the appropriate bag.
After your team....can catch and throw under pressure and....learns the proper defense , it is an easy out.
Sluggers is absolutely correct IMO. Although implied, I just added the bolded part above to recognize that different age groups/ability levels are valid considerations.
