Siem looks assured of Augusta invite

Siem overcame a shaky start to the final round, when his four-shot lead was quickly erased by Mikko Ilonen, before eventually prevailing by three strokes.

Siem’s third European Tour success could also be further sweetened by a first appearance at Augusta in a fortnight with victory likely to send him into the world’s top 50.

That would be enough to secure an invitation to the Masters, although he will have to await the final results of the Shell Houston Open before booking his flights to Georgia.

“That will be unbelievable,” said Siem. “It’s been my dream since I was a kid so if that comes true it will be unbelievable.

“It would be wonderful to play the Masters.

“I just want to be on that ground. I’m not going to cry but it would be very emotional.”

A third 73 of the week, on top of Saturday’s score of 70, saw Harrogate’s John Parry finish on 289, 18 shots adrift of Siem.

Malton’s Simon Dyson shot a final-round 67 to finish in a tie for 11th at the Indonesia PGA Championship on 14 under par.

Thai teenager Ariya Jutanugarn showed great composure to fight back to the top of the leaderboard and claim victory at the Lalla Meryem Cup in Morocco.

Jutanugarn, 17, prevailed against fellow teenager Charley Hull of England.
