Wyndham Clark took out his frustration Friday night on the member locker rooms at Oakmont Country Club, site of the 2025 U.S. Open.

Former U.S. Open champion Wyndham Clark said he “deeply regrets” the damage done to the century-old locker he was using at Oakmont during the U.S. Open, his second act of frustration that caused damage at a major this year.

Professional golfer Wyndham Clark on Thursday expressed regret for his behavior at last week’s US Open after reports on social media circulated that he had caused damage to the venerated course’s locker room.
