More obstruction

[Andy]

This HS season, I have been really working on seeing and calling obstruction because I believe that several types of obstruction are missed. I think that we have discussed the topic several times on the different boards. I had this play last night in a HS V game. Let me know what you all think.

R1 on first, ball hit back to F1. F1 turns to throw to second but throws the ball to the third base side and over F4. F4 reaches for the thrown ball and falls down on the third base side of second base as the ball is rolling into centerfield. R1, seeing the overthrow, rounds second with the intent of going to third and stumbles over F4 still on the ground. I am PU and have trailed the play up the first baseline. I am moving across the field to cover the play at third when I see R1 stumble over F4. My left arm goes out for the obstruction call. R1 made it to third safely, so it had no bearing on the play.

My concern is if this is really obstruction. R1 got to where F4 was on the ground before F4 really had a chance to get out of her way. My reasoning is that once the errant throw got by F4, she is no longer involved in the play and is subject to obstruction.

Thoughts?
