Wyndham Clark is apologizing for the damage done to the century-old locker he was using at Oakmont during the U.S. Open.

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.

Wyndham Clark made headlines last week for having an outburst at a second consecutive major championship, and the PGA Tour golfer has once again issued an apology.
