Wyndham Clark carded an 11-under par final round of 60 to win the CJ Cup Byron Nelson by three shots and finish 30 under par.

The American becomes just the 10th man to finish a four-round tournament 30 under or better since 1983.

Clark, who had carded rounds of 66, 63 and 65, scored an eagle and nine birdies to overtake overnight leader Si Woo Kim.

The 32-year-old’s approach shot to the 18th left him with a two-and-a-half foot putt for a three, and he sank his attempt for a fourth PGA Tour title and a score of 254.

South Korean Kim, who went round the par-71 course in 60 on Friday, only managed a 65 to drop to second on 27 under, with world number one and defending champion Scottie Scheffler two shots behind in third in Texas.

Clark, the 2023 US Open champion, last won on the PGA Tour in February 2024, at the AT&T Pebble Beach Pro-Am.
