I Took A Stroke From The Bunker And My Club Hit The Grass Face On The Backswing. Is That A Penalty?

Club strikes grass face of bunker on backswing.

You’ve hit what you thought was a good drive and are wandering up the fairway expecting to have a relatively straightforward approach to the green.

But there’s no sign of your ball. Surely it couldn’t have reached the bunker… you thought it was out of range. But you’ve hit it so well that it’s rolled out and toppled just into the sand.
