Here's the OBR rule. FED is similar.
If, however, the runner has contact with a legally occupied base
when he hinders the fielder, he shall not be called out unless, in
the umpire’s judgment, such hindrance, whether it occurs on
fair or foul territory, is intentional. If the umpire declares the
hindrance intentional, the following penalty shall apply: With
less than two out, the umpire shall declare both the runner and
batter out. With two out, the umpire shall declare the batter
out.
So if the batter is called out, is that considered an AB? How is that scored?
