DeChambeau’s participation in the Open in doubt after two-stroke penalty

• American punished for improving line of his swing

• Sanction moves DeChambeau out of second place

Bryson DeChambeau's ongoing participation in the Open Championship is in doubt after extraordinary scenes at the conclusion of the 32-year-old's second round at Royal Birkdale.

DeChambeau was handed a two-stroke penalty for improving the line of his swing in thick rough, and the scenario prompted a furious response from the American. The sanction shifted him out of second place and an initial position of one stroke behind the leader, Lucas Herbert.
