Bryson DeChambeau's rules controversy at The Open: What happened, why was he penalised and how did he react to decision?

Bryson DeChambeau has been criticised for ‘making himself the story’ by the way he handled a two-shot penalty during his second round at The Open.

The two-time US Open champion appeared to be a shot off the halfway leader Lucas Herbert after rounds of 67 and 66 at Royal Birkdale, only to be embroiled in a lengthy rules discussion after his second round.

DeChambeau was seen in a heated conversation with R&A officials at the par-four fifth, where he had been adjudged to have improved the area for his backswing, and eventually was handed a two-shot penalty for the incident after further talks in the recorders area.

The penalty turned his bogey into a triple-bogey seven and dropped him three off the lead, with DeChambeau then going to hit balls on the practice range - in near darkness - before leaving the course around 10.30pm without speaking to the media.
