Runner at 2nd and 1st, no outs ball hit to shallow LF, the runner at 2nd goes half way, the ball hits just in front of the LF and just behind the SS, the SS throws the ball to 3rd forcing the runner out.
The runner however gets up and starts to run home, the 3rd baseman throws home (apparently not knowing the runner has bee called out, even though the ump gave a hand signal but nothing verbal), the runner(who I will also assume didn't know he was out) gets in a run down between 3rd and home. Finally our catcher realizes that the runner was called out, and attemps to throw the ball to 3rd because the runner that was on first has now attempted to advance to 3rd, our catcher has to throw around the runner who has already been called out.
I say the runner trying to advance is out as well because the runner that was called out initially caused a play to be made on him even though he was already called out, and because on the throw back to 3rd, he obstructed our catcher.
