Last night I had a first. A fairly well played HS fall ball game, pretty competitive and if not for one big half inning we would have probably been out of there in about 1:30.
R1, I'm in the B position. Pick off attempt runner gets in a pickle between 1st and 2nd. My partner hustles down the line to cover the 1st base side. We have an overthrow back to first and a lot of foul territory. R1 rounds 2nd and attempts for 3rd, F3 makes an excellent throw to third and now R1 is in a pickle between 2nd & 3rd. As I take the runner towards 3rd, my partner hollers he got the 2nd base side.
Wouldn't you know it, the ball gets away again good throw, bad fielding and it gets away toward right field. R1 is now heading home. I take the runner towards the plate F9 makes a great throw to the plate and now we have a 3rd pickle situation. My partner yells he's got 3rd and I stay at the plate area.
Next relay to the plate the runner dives for the plate, I'm there and get the out at the plate.
I don't think you'll find this in any mechanics manual, but it worked for us.
Sometimes you just have to umpire.
