How is your mechanic...

Been thinking about mechanic on swinging 3rd stikes.

I know the ruling but wanted to get your mechanic on what you do when the BR cannot run.

I had a situation 2 years ago I can't seem to get off my mind.

Situation: R2 and R1, 1 out, 2 strikes on the batter. Pitch is in the dirt, batter swings, strike 3. BR takes off toward 1st base as all other runners take off. PU makes no call on the BR (I assumed there were 2 outs), the catcher throws to 3rd which beats the runner for the force out, so I thought(no tag was applied).

Anyway, offensive coach comes out and states there are only 2 outs. I immediately called time and told all players to stop where they were. I go to my P and ask him how many outs there are. He states, 2. Well you know the rest, R3 and R2, 2 outs...

I come out point, signal out and voice, batter is out, batter is out!

Is that the correct mechanic?

What do you do?
