Patrick Reed secured the WGC-Mexico Championship with a one-stroke victory on Sunday.
The American produced a fine finish at Club de Golf Chapultepec, birdieing four of his remaining seven holes on his way to a four-under 67 in the final round.
Reed finished at 18 under, a shot clear of Bryson DeChambeau, who carded a six-under 65.
It marked Reed's eighth PGA Tour win and first of 2020, and second World Golf Championships success, with the other coming in 2014 when this event was called the WGC-Cadillac Championship.
Reed made three straight birdies from holes 15 to 17 to grab control, closing out victory despite a bogey at the par-four 18th.
"It's very rewarding," he told NBC.
"My team and I we've worked so hard through the end of last year and also the beginning of this year and we kept on feeling like we were playing some good golf, just we weren't quite able to get over that hump.
"To come back and win my second World Golf Championship, especially with how I had to finish basically 15 onwards. The last hole was ugly but it was what I needed just to get the job done and at the end of the day just putting yourself in these positions on Sunday is just unbelievable, it's a great feeling.
"I can't wait to go home and celebrate with the little ones and my wife and bring them home a trophy."
Spaniard Jon Rahm (67) and South African Erik van Rooyen (70) finished tied for third at 15 under.
World number one Rory McIlroy could only manage a closing three-under 68 to end up fifth a further shot back.
Overnight leader Justin Thomas struggled to a two-over 73 that saw him finish tied for sixth alongside Hideki Matsuyama (67) and Tyrrell Hatton (68).
Thomas made three bogeys on his front nine before adding a double-bogey at the par-four 10th and dropping another shot at 13.
