Looks to be OBR 7.06(a)
7.06
When obstruction occurs, the umpire shall call or signal "Obstruction."
(a) If a play is being made on the obstructed runner, or if the batter runner is obstructed before he touches first base, the ball is dead and all runners shall advance, without liability to be put out, to the bases they would have reached, in the umpire's judgment, if there had been no obstruction. The obstructed runner shall be awarded at least one base beyond the base he had last legally touched before the obstruction. (Which, would be 1st) Any preceding runners, forced to advance by the award of bases as the penalty for obstruction, shall advance without liability to be put out.

So my question would be "What made you think the BR would reach 2nd?" If the catcher is holding the ball why would you think another runner would make it to home safely if the F1 and the BR had not collided?

Sounds like the right fielder, F9, made and incredible play. Sounds like the BR probably was watching the flight of the ball also and probably was a contributor to the collision. He likely only would have went to 2nd had the throw to home gotten away from the catcher allowing R2 to score also.

I wasn't there but I think you may have "over" awarded.
