Trevino continued a phenomenal run of form by adding success at The Open to his recent victories in the U.S. Open and Canadian Open. His total of 278 was enough to edge out Lu Liang-Huan by one stroke.
Earlier in the week, there was a memorable interaction between Faulkner and his youthful caddie, as the Champion of 1951 paid tribute to fellow veteran Locke.
"If he was 20 years younger, he'd walk this. There's no question about it," said Faulkner of Locke, leading his caddie to respond: "What, even with Nicklaus and Trevino?"
"Yeah, he could beat those," continued Faulkner. "There was no one in America used to catch him. Wonderful temperament."
Fourteen years on from his fourth and final Open victory, Locke made the cut at the age of 53 and finished in a tie for 49th.
