Infield Fly if you don't call it immediately

[Lenny F]

Not calling infield fly does not negate the infield rule.
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.
