Brandon Stone closed with a one-under-par 71 on Sunday in the weather-shortened Porsche Singapore Classic on the DP World Tour to finish in a share of 20th at Laguna National Golf Resort Club.

After his opening 68, he produced an identical number for his second round to be in a share of 10th heading into the final round. Having made on bogey in the first round and two in the second, he inevitably made three in the final round to finish on nine-under for the 54-hole tournament.

That left him six behind the winner, Richard Mansell of England, who carded a closing six-under 66 to best Japan’s Keita Nakajima, who shot a 65, by one. Adrien Saddier and Tom McKibbin shared third on 14-under.

Mansell claimed his maiden DP World Tour title after finishing with a brilliant birdie. With the tournament reduced to 54 holes following Thursday’s washout, Mansell went into the third and final round one shot off the lead on 10-under-par.

But he soon hit the front after following up three opening pars with five birdies in a row from the fourth hole at Laguna National Golf Resort Club, heading to the turn with a two-shot lead.

And although he was joined at the top on the back nine, Mansell saved his best until last, two-putting from over 100 feet for a birdie at the 18th to sign for a closing 66 and finish the tournament on 16-under-par, one ahead of early clubhouse leader Nakajima.

Nakajima made seven birdies in a spotless 65 to surge into contention but was denied a play-off by Mansell’s heroics at the last.

Stone climbed into 73rd place on the Race to Dubai rankings with his finish.

Dylan Frittelli finished a shot behind Stone on eight-under in a share of 28th. He closed with a level-par 72, and he was on the same total at Louis Albertse, who had a closing 69.
