The right no-call?

[bainsey]

ASA slow pitch, co-ed.

Routine infield grounder. The throw, while well in time, pulls the first baseman off the bag, and never gets the out. The batter-runner goes over first base, making no contact with it.

I say and signal nothing. I simply wait for the batter-runner to "return" to first before calling her safe. Instead, she assumes she's out, and simply goes back to the dugout. I quietly signal out.

Did I handle this one correctly?
