You make the call

Interference, runner is out. No runs can score. If it had been less than two outs, all runners would have to return to the last base that they occupied at the time of the interference.

Unless your going to suprise us with some third world twist.....I agree with Tallump. This seems to be pretty straight forward interference.........

I knew it was simple and straight forward. However, the coach did not think so and of course he spent the next game of the tournament in the parking lot.
That simple "You don't know the *&##$$ rules." comment.

Of course this falls under the heading of "umpires do not eject coaches"..........we just "confirm their choice not to participate any further"..........

Good call.......and a deserved ejection.....pretty much anytime the word "you" is the starting word, you can expect trouble.
