Leaving field of play

[rharrell]

Had this happen in GHSA (NFHS)tournament this weekend. Batter swings for 2nd strike, I call strike. Apparently thinking it's her third, she heads for the dugout. I verbally give the count and also signal the count. She continues inside the dugout.

Is this an out for leaving the field of play? Should I have been more forceful and individually called back the batter?

Unrelated, it was a miserable hot day (heat index @ 105-110) and we lost some umpires and players to the heat. Nothing real serious, fortunately.
