Interference, Obstruction, or Incidental Contact?

[tankmjg24]

Alright guys, so this did not happen to me nor was I at the field. As a matter of fact I am in a different time zone than where the incident occurred. A good friend of mine was on the plate and he called me to see whether they got the call correct or not.

OBR rules (Little League) with a 4 man umpiring crew on a 12U game. There are 0 outs with R2. Batter squares around to bunt and the pitch is high and tight. The batter still attempts the bunt and is successful, however he is kind of going backwards due to the location and does not get a good run out of the box. The ball goes about 5 ft in front of home. F2 starts after the ball and the BR take offs for 1st and they make contact with both falling to the ground. F1 ends up picking up the baseball and tagging BR who is laying on the ground. R2 advances to 3rd.

Both coaches come out to argue and both coaches want interference called (poor offensive coach apparently does not know what obstruction is haha). The defense wanted interference on BR so that R2 would have to return to 2nd. The offense wanted obstruction on F2 and wanted BR on 1st and R2 on 3rd. The umpires huddled and ended up sticking with the no call and their rationale was that both were doing what they were supposed to do.

Now there are a few different rules floating through my mind that could possibly support a no call and possibly support an interference call. I see no support that obstruction could be called here as F2 is the fielder that I would protect, not F1.

So what do you all go with here? BR out for interference with R2 returning to 2nd or incidental contact?
