Russell Henley sealed a four-shot victory in the World Wide Technology Championship at Mayakoba as he cruised to a fourth PGA Tour title.
It was Henley's first win since the 2017 Shell Houston Open, and he tied the tournament low-scoring record – set by Viktor Hovland last season. Henley's final aggregate of 23 under was secured by rounds of 63, 63, 65 and a 70 on Sunday.
He finished four shots clear of the field, but after going bogey-free for his first 58 holes, Henley's first blemish for the week came with a six at the par-five fifth, adding another bogey on 16 to go with his three birdies.
Speaking to NBC after stepping off the final green at the event in Mexico, Henley said he was guided by experience of previous occasions where he has not been able to convert 54-hole leads into wins.
"Just tried to learn from my past, and my screw-ups," he said. "That's kind of what I took from the last two events this season – what am I doing wrong, and how can I get better with it.
"All those events that I haven't closed out [five times he has held the 54-hole lead and not won], they hurt. You don't know if you'll ever get to win another one, it's so hard out here.
"To come down 18 with a four-shot lead, it's really cool. I don't even know what to say. I felt very nervous this weekend, I slept on the lead both nights – I've never slept on a six-shot lead.
"You just don't feel the same as when you're practising at home, you can't create that environment that you get out here when you're leading at a PGA Tour event.
"I guess all the times I didn't get it done, I learned from it, and here we are."
Alone in second place at 19 under was Brian Harman, who posted rounds of 66, 66, 67 and 66 in an incredibly consistent week which included a hole-in-one on Friday.
Scottie Scheffler was two strokes better than anyone else in the final trip around El Camaleon Golf Club, shooting a nine-under 62 to fly up the leaderboard into a tie for third at 18 under.
Joining Scheffler at 18 under were fellow Americans Joel Dahmen, Troy Merritt and Will Gordon, as well as last week's winner of the Bermuda Championship, Ireland's Seamus Power.
Sweden's David Lingmerth joined Sam Ryder at 17 under in a tie for eighth, while defending back-to-back champion of this event Hovland was one further back, tied for 10th.
Collin Morikawa finished the week at 15 under, and former world number one Jason Day was joined by former Masters champion Danny Willett at 14 under.
