Thailand's Thanachot Thathandavas will take a four-shot lead into the final day of the MacGregor Hong Kong Junior Open Championship after firing a sparkling round of two-under-par 70. Hong Kong hopeful Steven Lam Tsz-fung was second following a roller-coaster round of 74, while Lionel Chan Chun-yan, who won the Kau Sai Chau Junior Open earlier this week, continued his fine form by carding a 75 and sharing third place with Malaysian Muhammed Arie Fauzi. Strong winds and frequent showers made low scores hard to come by at the Discovery Bay Golf Club, but 16-year-old Thanachot, a one-handicapper from Bangkok, handled the conditions admirably, recording two birdies and a remarkable eagle three at the par-five 12th to cruise into a comfortable lead. The 13-year-old Lam, who has dominated the local junior scene of late, was left to rue his chipping after mixing an eagle and two birdies with a disappointing six bogeys in his round of two-over-par 74. 'I made a few silly mistakes out there,' admitted Lam, who attends St Joseph's College in Mid-Levels. 'My approach shots were generally good, but my short game, and my chipping in particular, was poor. I'm going to have to improve that in time for tomorrow.' Lam, who also eagled the 12th after knocking his seven-iron approach to within eight feet of the pin, believes that although Thanachot holds the advantage, the outcome of the tournament is far from settled. 'Four shots is not a lot on this golf course; there are some good opportunities to make birdies but it's also easy to get into trouble,' Lam said. 'I'll have to play really well to have a chance, but I'm feeling good and I'm looking forward to it.' A close finish is expected in the girls' division after the first round ended with three players tied for the lead. American Kristina Wong, Thailand's Jaruporn Palakwong and Maria Andrea Legaspi from the Philippines all notched steady two-over-par rounds of 74.
