Justin Rose birdied the last two holes to win the Zurich Classic of New Orleans by one stroke and claim his seventh career PGA tour victory.
Rose shot a bogey-free six-under-par 66 in the final round to post a tournament-record 22-under total of 266 and came home one clear of American Cameron Tringale who had needed an unlikely eagle at the last to force a play-off, but could only manage a birdie at the par-five 18th.
The 2013 US Open champion was claiming his first success since winning the Quicken Loans National in 2014 and holed putts from 10 and 13 feet on the final two holes to guarantee his success.
Rose, who began the week ranked ninth in the world, has now won at least once in the last six years, the second-longest streak behind Dustin Johnson's eight straight.
Rose told Sky Sports: "On my way to the course this morning I was thinking, 2010, 2011, 12, 13, 14, and trying to work it out. Six years in a row is not easy to do and I'm incredibly grateful and proud of that stat."
It was a long Sunday at the TPC Louisiana as the players were up early to complete their third rounds after Saturday's proceedings had been curtailed by numerous disruptions for bad weather.
Playing aggressively on a soggy course, Rose - runner-up at the Masters earlier this month - made six birdies in the final round and played the last 66 holes without a bogey.
Rose made a fast start to it as he joined Jason Day at the top of the leaderboard, finishing with a seven-under 65 to sit one shot clear of Daniel Berger and Blayne Barber.
Back-to-back birdies on the sixth and seventh saw Barber move into the lead as the fourth round got going, but the American soon fell out of contention, bogeying the ninth and sealing his fate with a double bogey on the 17th after finding the water off the tee.
Jim Herman was the next to step up, making three birdies in a row on the ninth, 10th and 11th, but Rose responded with birdies on the seventh and eighth putting him one up.
Tringale, whose only professional win was at the Franklin Templeton Shootout last year, emerged as the biggest threat when he eagled the par-five seventh to join Rose at 19 under, and then nosed in front with a birdie on the eighth.
Rose, 34, missed a birdie putt by no more than an inch on the 12th to stay one shot off the lead, but roles were reversed on the 13th as Tringale bogeyed and Rose made birdie.
Rose, who finished in a tie for second place at the Masters earlier this month, stretched his lead with a birdie on the 17th but looked in trouble with a wayward second shot on the 18th.
But a wonderful chip from 41ft set him up for the birdie putt and he pumped his fist with joy when he sank it for a two-shot clubhouse lead following a round of 66.
"This is great to build on," Rose added. "The Masters was huge, but it's a second place.
"You can take a lot away from that, but to knock down those last couple of putts here, as a player you can really build on that and if I find myself in a good position in a major championship. I can look back at those and take some confidence."
Boo Weekley was one shot back from Tringale in third, while Day walked to the 18th tee needing an albatross to force a play-off, but could complete the par-five in regulation and finished tied-fourth with Herman.
