If it's the one where the ball hits the fence bounces up and lands on the other side of the fence, it's a HR.

I've read the rulings for Situation S and have no problem with any of them.

Can you clarify?

Page 61; 2019 case book. I think I created confusion by labeling my examples ABC before citing the case book.

In my OP; my 2(a) corresponds with Case Play 8.4.3.S(d). Ball hits the top of the fence and goes over. My 2(c) is a variant of this, as well.

My 2(b) corresponds with CP 8.4.3.S(b).

Here's the problem I have with the interps: A ball that strikes the top of the fence in fair territory is simultaneously a ground ball (it cannot be caught by a fielder for a fly out) and a fair fly ball (if it goes over untouched, it's a HR).
