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.

Clark’s damage at Oakmont came after he missed the U.S. Open cut, shooting eight over the first two days. A bogey on 18 Friday resulted in him missing the cut by a stroke. Since a T-5 finish at the Texas Children's Houston Open on March 30—his lone top 10 finish this year—Clark’s best finish was T-27 at the RBC Heritage on April 20.

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.
