Trailing runner tagged out after lead runner is obstructed

[sbatten]

ASA answers preferred because that's what I call.

Situation: Two outs. R1 on 2B, R2 on 1B. B4 hits a ball in the gap.

R1 is obstructed by F6, falls, barely makes it to 3B and stops. Umpire sticks out his arm and immediately judges that R1 and R2 (a speedy runner who was moving on contact) both would have scored easily without obstruction.

But trailing R2 didn't see what happened. She rounds 2B, advances almost all the way to 3B, sees R1 standing there, retreats toward 2B and then R2 is tagged out by the defense before reaching the bag.

What's your call?

• R2 safe or out?
• If R2 is safe, is she awarded home or some other base?
• If R2 is out, is R1 awarded home and the run counted, or does R2's out (being the third out of the inning) prevent R1's run?

My instinct is invoke the "dead ball, award bases" routine -- R2 safe, R1+R2 sent home -- BUT the ASA Rulebook is only explicit about the obstructed runner. It mentions the other runners with regards to awarded bases, not safe or out.

I am guessing there are helpful case plays in the ASA Case Book but I don't have it. Or if this has been discussed before, please point me toward the thread -- I tried searching and couldn't find it.

Cheers,
