Fleetwood had started the final round in second place, two shots behind Japan’s Keita Nakajima.

New Zealander Daniel Hillier – ranked 218th in the world – leapfrogged them into a surprise lead, after moving to seven under for his round, but was unable to recover from a double bogey six on the 14th.

Nakajima, meanwhile, could not summon up the fireworks of his third-round 65, and had to settle for his third second-place finish on the DP World Tour.

However Englishman Fleetwood, whose putter had run cold during a frustrating third round on Saturday, had a run of four consecutive birdies around the turn – from the seventh to the 10th – followed by fine birdie putts on the 14th and 17th, to go down the last with a comfortable two-shot advantage.

His latest victory ensured he would qualify for the season-ending tournaments and continued a recent run of form that also included a star turn in Europe’s Ryder Cup win over the United States in New York.

“There’s been plenty of times when things haven’t gone my way, but the last two tournaments I have been in contention in I have won, so maybe things are starting to even out a little bit,” added Fleetwood following the latest achievement of a remarkable season, in which he has claimed eight top-10 finishes on the PGA Tour.

Fellow Englishman Alex Fitzpatrick rolled in for a birdie at the last to finish with a third consecutive round of 67, which moved him to 18 under and a tie for third place alongside Ireland’s Shane Lowry.

Viktor Hovland finished his week with a flourish, moving up to 17 under and a share of fourth place after chipping in for an eagle at the last.

Rory McIlroy, meanwhile, finished in a tie for 25th on 11 under.
