The dreaded R1 on 2B SS and runner collide

[first2third]

Situation- two out R1 on 2nd base hit up the middle SS turns to go towards the ball and collides with R1. There was no way that SS is going to field the ball. I have obstruction. It was in a high school semi final game. The defensive team runs off the field and the crowd is yelling great call, and the offensive team vacates the bases and goes into the field. The coach comes out between innings her wheels are turning in her mind as she walks. She says you had obstruction didn't you? Yes. But we just ran off the field? Yes. So it's our fault? Yes. Then she went back to the dugout. I asked my partner if I blew it, of course he said no he agreed with the obstruction. But he is less experienced and I can't tell if he was just saying that to kiss up or if he really felt that way.

Here is the interesting thing. I think in ASA I got the call wrong but in College and High School I got it wright (I think). Let me know how you see it.

College rule: Interference "reasonable opportunity to play the ball...ball must have been playable."

Fed rule: "batted ball which the defensive player has an initial play"

ASA rule: "fielder attempting to field a batted fair ball"
