It's true that with Fed's FPSR there doesn't have to be a play. Still, on the bump the OP describes, there's no way this is INT. Fed defines a legal slide, and the BRD says to call NCAA the same way. However, in calling INT on a sliding runner, Fed is stricter than NCAA (this is according to the BRD; I don't do NCAA baseball).

I don't know whether NCAA requires a play for INT, but OBR certainly does. Even with the recent "change" in that INT at 2B is actually being called, there has still been something resembling a play somewhere.

I'm glad I played long before all these INT rules came into being. Everything was called pretty much according to OBR, and—strange—there were no problems. Neither INT nor OBS was an issue at all. In fact, except for a couple of swings in which the bat hit F2's glove, I can't remember a single call of either INT or OBS.
