force out question

[k2explorer]

Hi,

I have a question. There is a runner at third with 2 outs. A dropped third strike to the batter. The runner at third ends up scoring before the catcher throws to first to get the batter-runner. My question is, does the run count?

I have always understood that if the third out was a force out, the run does not count. I was a base umpire the other day. This occurred and the plate ump said the run scored and no one argued with him.

Thank you.
