HS game, no outs, no runners

Pitcher throws a ball in the dirt that bounces in front of the plate and is caught by the catcher, the batter has swung. the umpire hollers strike 3 with his fist in the air. Coach instructs catcher to throw the ball around . Batter ruled safe at first. What should the proper sequence have been? Confusion caused by third strike call then fist in the air.
Thanks
