It looks like I am in the minority, but I think the call was correct. I recorded the game and watched it several times. The ball was in the circle and the runner stood for two full seconds before moving toward the base. I don’t know about ISF but in ASA ISA and FED, the rule states the runner must be moving immediately when the ball is returned to the circle. I give the runner about two seconds and it appeared the Umpire making the call did the same. There is no mention of how far the runner is off the base. As far as ending the game this way it was unfortunate, however, if you will call it in the first inning you should call it in the final inning. The call earlier in the game when the runner was called out for leaving early at first base was more border line than this one.
