OBS affects other runner

[greymule]

How would you call these three plays?:

Play 1

Abel on 1B. Baker gets a hit down the RF line, looks like a double. At full steam, Abel rounds 2B and Baker rounds 1B. However, Abel has to dodge F6, who is standing in the basepath. You call and signal OBS as Abel slips to one knee. Abel gets up and starts toward 3B but decides to retreat to 2B. Baker is almost to 2B but sees Abel retreating and himself retreats safely to 1B.

Where would you place the runners?

Play 2

Same play, except that Baker is put out retreating to 1B.

Play 3

Same play, except that Baker continues to 2B and slides in safely. With both Abel and Baker in contact with 2B, F4 tags them both.
