Hatton shot five-under-par 67 to finish on 19-under, capping a week when he shot in the 60s every round around Wentworth's storied West Course.

Veteran Scott Hend finished off a fine week's work with a 68 that left the Queenslander in equal 10th place and top Australian. Compatriot Wade Ormsby, who had started brightly with an opening 68, ended up with a four-over-par round that left him 54th overall.

The 47-year-old Hend finished up on 10-under, nine shots adrift of Hatton, who enjoyed the biggest win of his career.

It even topped his victory at the Arnold Palmer Invitational at Bay Hill in March that marked his breakthrough in the United States, where he has been playing for the past nine months either side of golf's hiatus for the coronavirus pandemic.

Hatton used to attend this tournament – the elite event on the European Tour – as a child, and recalled this week the time he came to Wentworth as a five-year-old with his father and was nearly struck by an errant tee shot from Vijay Singh.

"It's unbelievable," said Hatton, who acknowledged in a walk along TV interview during the round that he was nervous. "This was a goal of mine, to win this tournament in my career."

Hatton, who has sparked debate among more conservative golfing figures this week by wearing a hoodie during the tournament, came into the final round with a three-stroke lead and was only really challenged by Frenchman Perez, who moved into a share of the lead with Hatton after an eagle on the par-five fourth hole.

Bogeys at 13 and 17 ended the challenge of Perez, who didn't pick up a shot in his final six holes and shot 68.

Hatton gave Perez a glimpse of an opportunity by bogeying No.13 – his only dropped shot of the round – but bounced back by making birdie on 15 and 18 to ultimately ease to the win.

It is Hatton's third victory at a Rolex Series event and he is set to move into the top 10 in the world for the first time.
