The following scenario occured at an American Legion game. Although I don't dispute the call one way or the other I would be interested in some knowledgable opinions.
Bottom of the 9th. 1 out, bases loaded, home team is behind 10-9. Batter hits a deep fly ball to RF which is caught. Runner at 3rd tags and runs home, runner at 2nd does not tag thinking the ball will not be caught. The RFer throws the ball into the SS who in turn throws the ball to the pitcher. The 2nd baseman is screeming to throw him the ball because the runner at 2nd didn't tag up. Pitcher throws to the 2nd baseman and the base ump imediately calls the runner out. In effect this is a double play force out. The big question is, does the run count? Is it a force or a timing play?
The ruling at the time (after some disscussion between the 2 umps) was that it was a force out and the run was disallowed.
