What would you do?

[Tim C]

Again, I might not have this right but:

Once the batter-runner has crossed over the bag he has "legally acquired" the base if F3 was off the base as in this play. I think, therefore, the correct mechanic is signal "safe" with no verbal comment.

Any other signal or comment alerts either team unfairly.

I may be confusing this with something else all together.
