If David Gleeson has another Groundhog Day, the rest of the field would be better off playing in the ubiquitous casinos that dot every corner of this city than turning up for the third round of the Macau Open today. The on-fire Australian fired a second successive seven-under-par 64 for a halfway total of 128 to take a commanding five-shot lead. The others can only hope his dream form won't last at the Macau Golf and Country Club. But Gleeson insists he has more magic in his armoury as he sets his sights on winning the US$500,000 event and claiming only his second win on the Asian Tour. 'I'm in the box seat right now and my aim is to win this tournament by as many shots as I can,' said Gleeson, who is hoping to carry this form into the lucrative HSBC Champions tournament in Shanghai, in a fortnight. Tied in second place on an aggregate score of 133 were India's Anirban Lahiri, Yasin Ali of England, Lin Wen-tang of Taiwan and birthday boy Adam Blyth from Australia. Blyth turned 27 yesterday and celebrated it with a six-under 65. But Gleeson took the cake. Unlike on the opening day where he carded an error-free round, Gleeson showed he is human, too, with one bogey yesterday. It made his overall effort even more impressive as he rolled in eight birdies in a stunning putting display. The performance even left Gleeson a trifle bemused. 'I have been 12-under after two rounds before, but never 14. I feel I'm in tune with this course,' Gleeson said. 'My goal this week was to come here and do a good job. Now that I have got a good start, I won't play defensively as that might come back and bite me.' He added: 'I will continue to be aggressive, but this is a tricky course where you have to make a lot of decisions at every hole.' Rookie Lahiri, 21, has found his footing on the Asian Tour this season, and recorded a strong 65 yesterday. 'I putted well for a change,' said the Bangalore-based golfer, who is playing in his ninth event on the Tour. 'In the first five or six events this season, I was still trying to come to terms with the environment but now I feel much more at home on the Asian Tour and my game is slowly falling into place.' Welshman Rhys Davies carded a solid 68 to be joint-third in a group of four, six shots adrift of Gleeson, and said he hoped to emulate the Aussie's performance heading into the weekend. 'Gleeson had two good days here,' said Davies, who finished in the top-10 at the Asian Tour's Qualifying School. 'We are at the halfway stage and there are still two days to play. He was hot in the first two rounds and I hope it will be my turn over the weekend.' Meanwhile drawcard Zhang Lianwei made up for a disappointing first round where he shot a one-over 72, with a more composed 67 yesterday. But the former China number one's chances of winning a third Macau Open look slim considering that he is 11 shots behind Gleeson.
