			Bob, in the original example/question, F9 fielded the ball and threw to F4, and in fact threw BR out.  That is a "type A" obstruction.  It still looks to me like F3 obstructed BR and the play at 2B put him out.  
 I would go for a simple obstruction call, give BR 2b and get on with the game.  The fist base coach in this example was right-on the whole time.
