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 said: “This is great to build on. 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 Jim Herman and Australian Jason Day tied for fourth on 19 under.
