Runners on 2b and 3b with 1 out. Fly ball to short center caught for the 2nd out. Outfielder throws ball towards home plate. Runner is tagging from 3rd. On deck batter is walking onto the field of play (out of the on deck circle) and the thrown ball hits him before the tagging runner crosses home plate. Umps had not called time so ball was considered live. I assume this is intereference of some type. Is the runner on 3rd called out? Not sure what is done in this instance. Thanks
