Mechanics from "A"

[GarthB]

If you decide to go in, go in. If you can't run 30 feet while the runner is running 90, you don't have the wheels to umpire. Pivot, either traditional or AAA, watch the touch at first. No need to be watching the pitcher. Look to the ball. For a play you need a runner and a ball. Let the ball direct you to the next play, if any, not the runner.

If there will be a play at second you have plenty of time to set up in the working area behind the mound, come set and make the call. From here you have the perfect view of runner, base, ball and tag, unlike the view you would get if you were playing catch up from working outside the base line. AND, you are in position to take the runner to third if he has the opportunity to go.

I know of no school or system of mechanics that recommend staying outside the baseline and playing catch-up, at least not on a 90' diamond.
