I should know the answer, but . . .

This is fixable --- but one thing to bear in mind is that you should decide to fix it without considering what happened after the play developed. Otherwise, if you use the "fix it only if the defense gets a cheap double play out of it" mentality (one I've heard often), then you've created a situation where only the defense can be harmed by your mistake - an inequitable situation.

In all of these but B and F, you should put Able and Baker on 2nd and 3rd, Charles is out.

On F, if you'd called IFF, you have exactly the same sitch - runners off bases when the ball is caught. I might be inclined to leave F alone, unless I am POSITIVE my lack of call is what caused the runners to be off base. (Or, put better, they should not be halfway on a pop up to pitcher anyway, whether IFF is in effect or not).

On B, there's nothing to fix - everyone is where they should be.
