Marcel Siem led from start to finish to capture the Hassan 11 Trophy at Agadir in Morocco but his invitation into next fortnight’s Masters is on hold as he waits to see how Sweden’s Henrik Stenson performs in today’s final round of the Shell Houston Open.

Siem won his third Race to Dubai title holding off a final round challange from Finland’s Mikko Ilonen and former winner, David Horsey.

Siem, who carded a last round 70 to win by three shots at 17-under par, went into the event lying 72nd in the world and will move into the top-50 with victory.

However the German, who is looking to join double Masters winner and fellow countryman Bernhard Langer along with Martin Kaymer in the season’s first Major, will have to wait to see what Stenson does in Houston.

Stenson is currently lying 53rd in the world but only two shots from the leading duo of Americans Bill Haas and Stewart Cink.

If Stenson wins or finishes top-3 he could very well knock Siem out of the top-50.

“I am so happy right now,” said Siem, who was presented with a jewel encrusted gold dagger by His Royal Highness Prince Moulay Rachid, the Crown Prince of Morocco.

“It was a big day for me and there was a lot of pressure out there. The guys really came at me, especially Miko who got to 15 under and tied with me at one point. I am very happy that I stayed cool and calm and finally made the birdies to turn the pressure back on the guys behind me.

“Hopefully this is enough to get to the Masters. I have to wait and see what the guys in America do but I am getting goose-bumps just thinking about it. It would be amazing.”

Siem also revealed that he was helped over the line by German golf’s greatest ever player and two-time Masters Champion, Bernhard Langer, who he called on Saturday night for some final round advice.

“I spoke to Bernhard last night because I have never been in the situation of going into the final round with a big lead and I just wanted to know if he had any advice on how to cope with that,” he said.

“I wasn’t sure if I should play defensive or aggressive but he said just play your game and play the way you have been for the last three rounds because you are in good shape and you shouldn’t change anything or have any fear. Don’t make any mistakes or bad decisions. He also told me not to look at the leaderboards for the front nine but then have a look after that in case you need to react.”
