Timer screw up, did I handle it right?

I agree with the Z-man. Put back 8 seconds, and go back to point of original throw-in. Yes, it sucks, because B can now re-assess their decision about pressing. End-of-game plays like this can have an unintentional large impact on the game.

I also like Z's suggestion about reminding the table crew that in close games, their best way to finish the game is to get the timing correct.
