Mechanics - Swipe Tag at First

[Rich]

...teaching 90 degree angles a while ago.

The "correct" mechanic is sometimes referred to as 2SF, or 2 steps fair.

This puts you on the line, a good position for pulled foot and swipe tags.

But, you have to watch for the quality of the throw and be prepared, as the base umpire, to shift into a better position.

As the base umpire in A, you should NEVER have to ask for help from the plate umpire, unless you weren't prepared to adjust for a bad throw.
