Assuming a right-handed thrower at 1B, should first baseman have back toward second base, or RF fence when taking a pickoff from catcher?
If you have back towards second and the throw is behind the first baseman the ball could end up in right field.
I prefer them stand facing the catcher about two feet inside the baseline just in front of the bag. Let the throw dictate which way she turns, but I like the throw to come glove-side so they turn glove-side to make tag
We had a first baseman who did the exact same thing. I showed her that when doing this she lost sight of the base runner. So, I said do what you normally do and I will show you what will/can happen. Runner takes lead,catcher throws down, first base turns back to second base,catcher throws ball, catches ball goes to make tag but, the runners at second. If first baseman faces second base or catcher this couldn't/wouldn't happen.should first baseman have back toward second base,
That makes me think. ... A runner diving back doesn't have the same ability to have her body avoid the tag the way a base-stealer would (ie, hook slide) because it's a bang-bang play. Therefore, the need to make the tag right at the base is not as imperative. Is that fair? If that's somewhat the case, then the catcher should not worry about making a pin point throw. Rather, she just needs to release quickly and keep the ball kinda low, basically throw right at the first baseman (not the bag, per se) and the first baseman can position herself to the throw to make the tag at the quickest point on the base path, whether that's 3 inches or 3 feet from the actual bag. And as you said, the baseman can face the catcher and go left or right, whichever feels best.
How does that theory sound?
As far as coverage positioning for a RH throwing 1B, my preference is to have them take an extra step and set up in foul territory (w/ their back toward the RF foul line fence) so that they don't have to turn their back and lose sight of the runner. But, regardless of set up, the 1B and ALL other IFers need to be taught to wait for the throw at the bag and bring the tag straight down rather than reach forward toward the plate then swipe back, which is far slower.
Runners diving back to first on a pick off attempt should be taught to go for the OF side of the bag to make the tag more difficult.
