The mechanics of the "No doubles defense"

When a tying or go ahead run comes to the plate or reaches first base late in the game this defense is considered by coaches. What is it? What do you do?

Here is what occurs.

For all intents and purposes it is a prevent defense in baseball. The outfielders are moved out of normal depth and situated in a much deeper alignment that is to prevent a double. The wing outfielders slide deeper and into the gaps while the center fielder goes staright back and deep. The corner infielders guard the lines to prevent the double down the lines. All of these changes open up the field of play for more possible base hits. However, it's premise is to guard against the big hit or extra base hit.

There are also subtle nuances of the defense.

The first nuance is that the outfielders should not dive at a ball. A dive could result in a double while allowing the ball to drop safely would result in a hit but certainly prevent a double.

The second nuance is that the 1B needs to come off the bag to catch all low, errant throws rather than trying to make a great play. This thinking coincides with the "no dives" thinking in that if you at least catch the ball you won't get a double. You may not record an out but at least you won't give the team 2B as well.

I'm not suggesting that this defense is a prudent defense in all situations as mentioned above but it should at least be considered.
