WestMichBlue, MarkPSkins, and Al are all on the right track, but let me explain what mechanics we're teaching at the high school level.

WestMichBlue talks about taking two steps into fair territory to make the call. We are advocating using the method known as the OSF method. That is, we want the umpire who starts in 'A' to move into a position that is One Step Fair. This is the method being adopted by many of the Major League umpires.

I like to start 25 feet behind the bag. Then when I take my walking steps (2) during the delivery, I can move inside with two normal strides and be 20 feet from 1st and just inside the baseline. I recommend at least an 18-foot distance but 20 feet is even better. With the OSF method, the BU should never have to go for help with a pulled foot or a swipe tag.

Watch the fielder throw the ball and as the ball leaves the fielder's hand (and you're certain the ball's not heading directly at you), turn your focus to the front edge (side closest to Home) of 1st base. Now you're concentrating on the bag and can see the runner in your field of vision. Listen for the ball hitting the mitt while you're watching the bag/feet.

As MarkPSkins says, don't call the play too soon. I never make a call until the runner has passed the base, even if she is out by 30 feet. Slow your call down by taking a picture (snap shot) of the play, rewinding the film, then playing it back. Seasoned and polished umpires use the same rhythm for most all called. Actually, the closer the play, the quicker the call should be. But always give the fans the chance to make the call first in their heads. "Quick" umpires do a disservice to the game by not allowing the spectators to compare their judgment with the umpires because of the fast calls being made. That tends to give the impression that the umpire's mind was made up before the play actually happened.

Once you make the call, remain in your place for a couple of seconds staring at the bag (unless a wild throw forces you to move for a subsequent play). I see too many novice umpires immediately turn their backs to the play or look down at their indicators after a close call. That's basically telling everyone that they're not sure of the call.

Finally, in regards to Al moving into foul territory on balls hit between the 1st and 2nd basemen, I like to stay in the OSF position unless the ball is fielded so close to me that I would be interfering with the play if I did not move. If necessary, I would stay on the foul side as adjust my position accordingly, remaining at least 20 feet from the base.

As a wiser man said, "It's not about proximity; it's all about angles".
