The first eight stagings of the mixed tournament that brings together junior champions from all over the world have been won by boys, and Jutanugarn, who is just 5ft 1ins tall, plays off plus three and drives the ball 250 yards, has been making a habit of beating them. Last year she also left them in her wake to win the R&A’s Junior Open Championship at Hesketh.

Her highlight yesterday was an eagle 2 at the ninth where she holed a wedge shot of 90 yards, but links golf is not to her taste. “I don’t like the wind, the rough, the greens - everything. I was just lucky,” she said. Asked about her win at Hesketh, she added: “I was lucky there too.”

Jutanugarn, who is still at school, has just joined the national squad and hopes to play for her country in the South-east Asian Games in Laos and the Asian Games in China before trying to get lucky yet again on the LPGA Tour in the United States.

Fortune did not smile, however, on Scots David Law, who had a 78 for a 16-over-par aggregate and 19th place, and Jack McDonald who had an 81 to finish 22 over and 36th out of the 57-strong field from a total of 34 countries.
