AUGUSTA, Ga. (AP) — Wyndham Clark was not just unperturbed after a first-round 73 at the Masters left him eight shots back of Bryson DeChambeau on Thursday. The U.S. Open champion was brimming with confidence that he could still overtake the LIV Golf star.

“We’ve got 54 holes. In LIV Golf they only play 54,” said Clark, taking a swipe at the Saudi-funded tour and its three-round format. “We’ve got a lot of golf left. As you can see, someone shot 7 under. I could do that tomorrow.”

Clark might be one of the most accomplished Masters rookies ever.

Not only did he triumph last year at Los Angeles Country Club for his first major, he also won the Wells Fargo Championship earlier in the year at Quail Hollow. Clark added another victory at Pebble Beach in February, finished second at both the Arnold Palmer Invitational and the Players Championship, and shot a final-round 66 in the Houston Open in his last start before the Masters.
