Let's call it what it is - will the rules folks ever append the "words"?

The original post was about what is traditionally used. Catcher's Interference is called Catcher's Interference in OBR. That is why we refer to it as such. There is also Umpire Interference. Should we then change that to Umpire's Obstruction? NO.

INT does not = immediate dead ball always. Batter's and Catcher's INT is not immediately dead.

OBS does not = delayed dead ball always. Type A results in an immediate dead ball.

I wouldn't look for OBR to change CI to CO anytime soon.
