I'm trying to get a handle on some things involving the way ASA handles OBS, and I'm wondering how these plays should be called. I realize that #1 is an easy "starter" question:

Abel on 1B, no outs. Baker hits a ball off the fence. Abel gets caught in a rundown between 3B and home.

1. Baker makes it all the way to 3B and stands on the bag. Abel is obstructed going back to 3B and is tagged out as he slides into 3B.

2. Same play, but F5 drops the ball on the tag, picks it up, and with both Abel and Baker on 3B, tags both runners.

3. As Abel is advancing toward home, he is obstructed 20 feet from the plate and falls down. You call and signal OBS. The ball gets a few feet away from F2, and though Abel could probably have scored, he scrambles to his feet and runs back toward 3B. Baker is standing on 3B when Abel arrives back safely. F5 tags both runners.

4. Baker makes it all the way to 3B. Abel is running back toward 3B and is a few steps away when he is obstructed. The ball gets loose, and Abel makes it back to 3B. With both Abel and Baker on 3B, F5 picks up the ball and tags both runners.

5. Baker sees Abel caught in the rundown and holds up between 2B and 3B. Abel is obstructed going back to 3B. Baker sees the OBS call and runs to 3B but is tagged out before he gets there.

6. Baker holds up between 2B and 3B. Abel is tripped going back to 3B and falls down in the baseline. You signal and call OBS. Abel, aware of the OBS call, sits on the ground 10 feet from 3B. Baker trots toward 3B and is tagged out. Abel is then tagged as he sits in the baseline.

I'm especially curious because in OBR, these are all easy. In every case, Abel is obstructed while being played upon, so the ball is immediately dead, Abel scores, and Baker (if more than halfway to 3B at the time of the OBS) gets 3B.
