OBS then INT

[SAump]

1) The runner committing interference is usually out, ball is immediately dead.
2) Interference rule suggests when the umpire cannot rule upon a play, here no throw to 2B - no play at 2B, the player closest to home can be ruled out.
3) By merely attempting to dislodge the ball at HP, we have an incidental malicious type of contact which may supersede obstruction.

I prefer ruling 7.06a obstuction only because the following interference ruling stinks, but it is what it is, as someone here would say.

I have a couple of thoughts that come from the OP. OBS was called on F5 - classical OBR 7.06(b), then R2, catcher and ball are all at HP. If R2 scores, then INT, run scores and BR is out (closest to HP as per SAump). My thought here is if R2 does not achieve HP before INT, max penalty applies - R2 out on INT, BR to 1b (thought process here is that defensive screwup does not relieve offense from the requirements to run properly).

Some rule sets (specifically Baseball Canada) state that time shall be called when a play is made on an obstructed runner (type b) and no further action can continue. Under that rule set, it would seem that R2, Catcher and Ball = play, so 'Tiime' and no INT. BR remains at 1b (otherwise why would catcher attempt throw to 2b?), and R2 scores if the umpire judgement is that he would have achieved HP in absence of OBS.
