obstruction-I think we need the call improved somehow

[mcrowder]

I do see your point.

I'm just thinking that any deviation along those lines is likely to confuse players (who panic any time we say anything other than ball/strike/safe/out), and weaker umpires (who would read your revised version of the rule and send people home that didn't deserve it, or kill the play at inappropriate times).

One note - on your example, if you're awarding home, and she falls down between 2nd and 3rd... she STILL gets home. It's not "too bad". If a rule like yours were in place, we could CERTAINLY kill the play if we decided home was going to be the award, since nothing that occurs afterward could possibly matter. Your comment that we can't kill it too soon implies that if the runner fell on her own between 2nd and 3rd, you'd revise your award. Please don't do that.
