Speaking of mechanics, do I understand this correctly? Runners at 1st and 2nd. Batter flies out to deep center. Runners tag and move up, then on overthrow, try for home and 3rd.
Two ump system, BU has BR until out and then assumes trail runner for tag up and play at 2nd, while PU covers lead runner tag up and play at 3rd. When the runners try for a further advance, BU should cover trail runner to 3rd as PU covers play at home.

The BU merely must make sure BR touches 1B and doesn't pass R2 prior to being put out. With a fly ball to center, the BU has R2, PU has R1 for the tag (unless the two communicate and swap assignments which is okay as long as they have it covered).

Assuming overthrow at 3B, the PU would have cut inside the diamond to make a possible call on R1 at 3B. Now inside the diamond and the ball on the outside, PU would stay inside and take R1 to the plate while BU has R2 to 3B.
