Obstruction?

[bigda65]

Big guy,

You are PU, Bottom 7, score tied, 2 outs, R2.
Batter hits a single up the middle and R2 goes on contact.
3rd base coach sends runner, meanwhile F2 setup right in front of the plate, while F8 has thrown a bullet.
Runner slides and comes up short, because he slid into F2's shin guards.
You count one-thousand one then catcher catches ball and lays a tag on runner.
You call time, "thats obstruction" and award runner home -- game over.

I am the defensive manager and come out and ask "Whatya got bigguy"?

What are you going to say??
