MACAU - Australia's David Gleeson blasted seven birdies on the way to a one-stroke lead in the opening round of the Macau Open on Thursday.

Gleeson a seven-under-par 64 to lead Thai duo Wisut Artjanawat and Udorn Duangdecha and Taiwanese brothers of Lin Wen-tang and Lin Wen-hong, who were all tied for second at the Macau Golf and Country Club.

"My goal is to win by as many shots as I can but if it doesn't work out that way, I will still go at it. I will adopt an aggressive approach here unless the weather makes a difference," Gleeson said.

In-form Australian Darren Beck, who finished runner-up at the Indian Open two weeks ago, carded a 66 to lie in joint sixth place in the 500,000-dollar Asian Tour event.

Beck lay alongside Taiwan's Wang Ter-chang and Kao Bo-song, Welshman Rhys Davies and Thailand's Wittawat Sae-ung.

Playing under calm conditions in the opening round, Gleeson was pleased to find his rhythm.

"It was a good start for me. I didn't make the putts but I stayed patient out there which was the key," he said.

"I kept my rhythm going throughout the day and fired seven birdies without dropping a single shot which was nice. When I play like this, I expect the scores to go down even lower.

"It wasn't fireworks out there but just a normal day of golf."

After a top-five performance at last month's Taiwan Masters, Thailand's Wisut was also in the birdies, nailing six with no bogeys.

"I've been with my new coach Shane Wilding and he has been instrumental in changing my swing. I am much more consistent now and in my first week with him, I finished in the top five at the Taiwan Masters," he said.

"That is great and I'm very happy with my performance at the moment. My putting was solid and I enjoyed a good finish with birdies in the last two holes," said the 26-year-old Wisut.

Defending champion Lu Wen-teh posted a 70 and was in a tie for 47th place.
