Thailand's Thongchai Jaidee continued to hang on to his lead at the top of the Asian Tour order of merit ladder after finishing in joint 39th position at Fanling yesterday. Thongchai won US$5,040 for his efforts which kept him safely at the top of the board on US$359,675. His nearest rival, Scotland's Simon Yates, finished five places below him at the end of the tournament, picking up US$4,480 prize for a US$306,718 total as the race for Asia's top money winner comes to a fitting climax. The Thai ace will be hoping to retain his lead at the upcoming Volvo Masters of Asia tournament in Kuala Lumpur, which is worth US$99,000 to the winner. Thongchai is the defending champion in the tournament. 'I am just thinking about improving my game. I struggled today because I was suffering from a bit of a back strain. I was not turning my body in my drives. I was using my arms and the balls were going left or right. I'm disappointed with my finish,' said Thongchai, a former paratrooper with the Royal Thai Army, who carded a three-over-par 73 yesterday. 'I am looking forward to the Masters tournament. As long as I stay in front of Simon, I will be okay. If he wins the tournament, then I will be in trouble. There's nothing I can do, if he wins it,' said the 35-year-old, who became Asia's number one after winning US$353,060 in 2001. He said he will fly his coach to Kuala Lumpur to help him with his swing. 'I need my coach to correct my faults and basically look after my swing. Simon [Yates] is playing well and I need to play well to beat him. I like the course at the Kota Permai Golf Club where I hope to successfully defend my title,' said Thongchai.
