FED: What happens to R1?

[DG]

Back to the original question. R1 was running, he was not disadvantaged by PU decision. He was thrown out by F2. If subsequent appeal of check swing was a strike he is out, if not he is safe due to walk. As BU I call the runner out and wait for the check swing appeal from PU. If it happens, and I think the batter swung, two outs. If no swing, no outs. The only correction to make is if the runner, after being called out, is tagged off the bag, and subsequent appeal is ruled no swing. Then, the runner would be disadvantaged by the call by BU.
