Kevin Kisner claimed his second PGA Tour title as he held off stiff competition to win the Dean and Deluca Invitational in Texas.
The 33-year-old, ranked 45th in the world, had finished in the top 10 in the tournament in 2015 and 2016 and held his nerve to par the 18th and win by one shot from defending champion Jordan Spieth, Sean O'Hair and Jon Rahm.
American Kisner went round in 66, with consecutive birdies on the 10th, 11th and 12th moving him clear at the top of the leaderboard at 11 under par.
He dropped a shot at the 16th but the chasing pack could not take advantage.
Kisner told Sky Sports 4: "I'm just honoured to be the champion here and to come back every year and see my name on that wall is going to be something special.
"I'm just happy to win any tournament but especially here, I love this place."
Kisner's previous win on the PGA Tour came at the RSM Classic in 2015. Then his winning margin was six shots but he had nothing like as comfortable a gap on Sunday.
Two-time major winner Spieth produced his best golf of the tournament to push Kisner all the way.
Spieth had dropped at least three shots in each of the opening three rounds but was flawless on the final day, starting with back-to-back birdies before making further gains on the fifth, 10th and 15th for a five-under-par 65.
O'Hair had six birdies in his round but dropped shots on the fourth and fifth cost him, while Rahm also signed for a four-under 66 as he finished in the top five for the sixth time in 10 PGA events.
Overnight leader Webb Simpson finished fifth, two shots behind Kisner, after struggling to a one-over 71.
England's Paul Casey, who started the day in a tie for second, also saved his worst round of the week for the final day.
An early birdie on the third had put him right in contention, but the 39-year-old dropped shots on the seventh, 10th, 14th and 15th to finish six shots off the pace.

Paul Casey holed a 23-foot putt on the 18th to leave himself within two shots of the lead at the Dean and DeLuca Invitational.
England's Casey, who is without a win on the PGA Tour since 2009, goes into the final day behind only leader Webb Simpson after recording a two-under-par 68 in the third round in Texas.
Casey is joined on seven under par by New Zealand's Danny Lee, while American duo Stewart Cink and Kevin Kisner are both one shot further back.
Defending champion Jordan Spieth is five shots off the lead on four under, as is Masters champion Sergio Garcia, who had three bogeys in a one-over 71.
Casey started the third round one shot behind four co-leaders.
He reached the turn in 36 following a dropped shot on the eighth but began the back nine with successive birdies.
Another bogey on the 12th threatened to stall his progress but he responded by sending his tee shot to within four feet at the par-three 13th for a birdie, before his superb putt on the last left him right in contention for a win on Sunday.
Whatever happens on the final day, Casey believes the improvement in his putting this week will leave him in a good place for the rest of the season.
"I've been working really hard on (putting)," he told the PGA Tour's official website. "In weeks I've putted well I've always had a chance to win or I've won golf tournaments.
"I haven't seen it yet but we're seeing it this week. There's one more round to go but it's looking good.
"I'm looking forward to not only tomorrow but the rest of the season. I'm very excited about how I've been playing."
Simpson, the 2012 US Open champion, dropped his only shot of the day on the eighth but birdies on the first, second, 10th and 11th saw him sign for a three-under 67.
Lee, who shot the week's lowest score on Friday, kept in touch with a 69. He had three birdies and three bogeys in his first eight holes, before recording nine successive pars and then draining a 16-foot putt on the last for birdie.
Northern Ireland's Graeme McDowell slipped back on day three, as a two-over 72 left him seven shots off the pace.
Masters champion Sergio Garcia and England's Paul Casey moved to within one shot of the leaders at the Dean & Deluca Invitational.
The pair each shot a four-under-par 66 to surge up the leaderboard in the second round in Texas.
Garcia had six birdies while Casey dropped just one shot as the duo ended day two on five under alongside Spaniard Jon Rahm and American Sean O'Hair.
The quartet trail major winner Web Simpson, his fellow Americans Scott Piercy and Kevin Kisner, and New Zealand's Danny Lee, whose 64 was the lowest round of the week so far.
Simpson birdied the last three holes to take a share of the clubhouse lead as he searches for his first PGA Tour victory since 2013.
Jordan Spieth will return at the weekend after missing the cut in his last two tournaments. The defending champion recovered from dropping shots on three of his first five holes to shoot a 68, leaving him four shots off the lead.
Garcia and Casey started the day four shots back and each birdied their first two holes.
The Spaniard dropped a shot on the fourth but picked up back-to-back birdies on the sixth and seventh. A bogey on the 10th was followed by a 12-foot putt for birdie on the next hole and another gain on the par-three 16th left him four under for the day.
Casey, who started on the back nine, dropped his only shot on the 12th but bounced back with a gain on the 13th. He then birdied the first and, after saving par with a 25-foot putt on the fifth, gained another shot on the sixth.
Northern Ireland's Graeme McDowell is two shots off the lead after a superb recovery on the back nine saw him follow up his first-round 66 with a level-par 70.
McDowell was three over at the turn, having three-putted for a double bogey at the third and then dropped further shots at the sixth and the eighth.
But a stunning approach on the 10th gave him a short putt for birdie, and further gains followed on the 11th and 14th.
It could have been worse for the defending champion as he closed his round with back-to-back birdies to finish level par, after a double bogey on the 15th had been followed by another dropped shot on the 16th.
Spieth has missed the cut at his last two events but had hoped a return to form was on the cards in his home state of Texas.
The 23-year-old bogeyed the second and fourth but returned to level par by gaining shots on the fifth and seventh.
A 38-foot putt saved par on the ninth before a dropped shot on the 10th was followed by birdies on the 11th and 13th to take him under par for the first time.
But he struggled on the par-four 15th, finding the bunker from his drive before his next shot ended up in a water hazard.
When he followed that up with a bogey on the next, the two-time major winner was seven shots off the pace, but an impressive end to his round will give him confidence for day two.
Northern Ireland's Graeme McDowell made a strong start to the tournament, with his four-under 66 leaving him a shot behind joint leaders Derek Fathauer, JT Poston and Kelly Kraft.
McDowell, who is without a top-10 finish on the PGA Tour this year, started on the back nine and birdied the 11th, 18th, fourth and seventh.
He goes into the second round in a tie for fourth with American Scott Brown and Spain's Jon Rahm.
Five-time major winner Phil Mickelson is one of six Americans lying a further shot adrift after he birdied the last three holes, while Masters champion Sergio Garcia is five shots back after an opening 69.
England's Paul Casey joins Garcia on one under after he double bogeyed the 17th.
