timing play on an appeal play

Question
one out, runners on 1st and 3rd. Batter hits a fly ball to outfield that is caught the runner on first is doubled off going back to first, but before that the runner on third scores. Does the run count?

Answer
Hi Bill,

Thank you for your question.  Your play is referred to as a time play or timing play.  The runner on 1B left before the fly ball was touched/caught, then was called out on a live ball appeal play.  Before she was doubled off, however, the runner on 3B scored, so the run DOES count.  Now, if the live ball appeal out would have occurred before the runner on 3B scored, then the run would NOT have counted.
