16U ASA rules. Bases loaded, 1 out. Batter hits pop up to 1st baseman. Umpire calls Infield Fly, batter out. 1st baseman drops ball. Runner on 1st takes off for 2nd, runners on 2nd and 3rd also take off to protect the trailing runner. 1st baseman throws home, catcher steps on plate but never tags runner. Eveyone agreed on facts so far. Intially umpire called runner safe because there was no tag, then changed his mind and said it was a force play, therefore, runner is out. Can some of the umpires on here give me the correct ruling and where to find it in the book? I thought the intent of the IF rule was to keep an infielder from dropping the ball - intentionally or otherwise and getting the easy double play.
