Infield Fly if you don't call it immediately

I disagree with the statemant made in an eairlier post that runners would be returned. Yes is is our responsibilty to call the infield fly or at least signal the situation but it does not remove it if not called/signaled. It is the teams responsibility to know the situation. Same as dropped third strike with runners on less than two out scerino. Lenny F.

OK, think about this a little more deeply. The IF is a call based upon the umpire's judgement. Now, what I call an IF, you may not. So, how would a runner or coach of dubious judgement know if it's an IF unless you call it? By making the declaration, you are letting the world know that the IF has been called. But, it's not positively an out, if it goes foul. And you can't call foul at all, 'cause now you really messed up. So, let the world know if it stays fair, the batter is out and the runners do not have to advance if the ball hits the ground.
