Greymule: "Apparently not so in Fed, where, as in OBR, the ball is dead as soon as an obstructed runner is played upon."

WMB: Are you sure? NFHS rule is very explicit in that the ball stays live until an obstructed runner is put out. (Identical to ASA.) Fielder drops ball on tag - no out - no dead ball.

You are right. I don't do Fed, and I misunderstood some of the postings. I guess the Fed/ASA difference is that in Fed a play on a subsequent runner removes the immunity from a previously obstructed runner who has made it to the base she would have reached. In an ASA caseplay, the immunity stays throughout the play. (However, the example deals with a ball thrown away, not a subsequent play on another runner.)
