Handling the ball in dead ball territory

[NCASAUmp]

ASA answers needed, but open to answers for other rule sets.

From another forum:

So, we had a little controversy in our last game. We played on a field with fences like this, ASA tournament.



One of our guys hits a ball into the gap, left fielder jumps the fence and the ball stays on the in play side. He reached back into the field of play and threw the ball in from out of bounds. So, basically he jumps the fence. Stops, turns around and reaches back over the fence. Grabs the ball and throws it in. What should be the ruling on this? The blue called it a dead ball double. As, any ball that goes under the fence, or bounces over is a dead ball double. Our argument was that he got an in the park homer on it, and he should have had every right to advance because the ball was still in play, however the fielder was not. Is this a catch and carry scenario?

So the fielder jumped over the fence into DBT, grabs the ground ball and throws it back in.

What say you all?

I say ASA 8-5-K.
