TEENAGER Daniel Lee Chi-wo pulled off a major upset by winning the first race of the 1993 Aquathon Series at Sha Tin, beating some of the territory's top triathletes. The 15-year-old completed the 800-metre swim just over a minute ahead of Con O'Kelly, Alan Wilson and Wan Shu-wah, all of whom came out of the water almost simultaneously. Daniel then put in a solid 5 km run and held on to win by just nine seconds from a strong finishing O'Kelly. Alan and Shu-wah were involved in an enthralling battle for the minor placing as they ran shoulder to shoulder until the last kilometre when the former pulled away to finish third. Daniel's bold victory showed how a year's instruction from Hongkong's world-ranked woman triathlete Ruth Hunt, the new coaching director of the Hongkong Triathlon Association, has benefitted him. Hunt said: ''Daniel is definitely one of the most promising local triathletes, being particularly strong in his swimming.'' Cheung Man-ho was an easy winner in the junior division which consisted of a 600 m swim and 3 km run. Andy Leung and Ryuichiro Iijima finished second and third, respectively. WINDSURFING JUNIOR international board-sailor Duncan Lai Tang-kan came within a whisker of his first open triumph but eventually had to settle for second place in the Tolo leg of the Mobil Hongkong Windsurfing Circuit. Duncan was one of the top favourites to win the event in the absence of national representatives Sam Wong Tak-sum, Ken Wong Hop-hi and Lee Lai-shan, who are in Europe for training and competitions. The Sear Rogers International School pupil lived up to expectations on the opening day of the two-day regatta when he took the overall lead after winning two of the three races. The winds, however, picked up on the second day and the 15-year-old was unable to control his sail and could only managed a fifth and a 15th placing in the two races. He had to be content with second place, overtaken by Tai Po-based Tang Luen-chun. ATHLETICS MILERS Chow Chi-keung and Simon Parsons stole the spotlight in the Hongkong Open Athletics Championships when they both beat the national junior record at the Wan Chai Sports Ground. Policeman Roberto De Vido won the race in four minutes and 19.54 seconds to shave 1.35 seconds off the record set by Paul Hawkins five years ago. Chi-keung and Simon ran the race of their lives to finish second and third respectively, both beating the junior mark of four minutes and 31.17 seconds. The two put up a grand race but Chi-keung packed a stronger finish and took the silver in four minutes and 27.27 seconds, beating Simon by 1.04 seconds. Olympians Neville Ku Wai-ming and Pat Kwok-wai once again proved they are the territory's leading sprinters as they finished one-two in the 100 metres. St Paul's College student Neville, fresh from his HKCEE exams, clinched the gold in 10.62 seconds despite having had less than three weeks' training. The national record holder was unlucky not to have beaten his own Hongkong mark of 10.59 seconds but said: ''Now that my exams are over, I can devote my attention to training and I'm confident of breaking my record within the next three months.'' TABLE-TENNIS POLAND's table-tennis veteran Andrezj Grubba put back the clock by winning the Epson All Stars tournament in Hongkong, his first major international title in five years. The 35-year-old Pole first saw off Sweden's former world champion Jorgen Persson in straight games and then toppled defending champion and world No 3 Ma Wenge of China in the semi-final. Grubba, the 1988 World Cup winner, rose to the occasion in the title match against fast-rising Chinese star Wang Tao as he won 21-15, 15-21, 21-10, 21-14 to amend for his defeat in last month's World Championships. VOLLEYBALL THE women's volleyball tournament, which started with the first round of matches at the Hongkong Coliseum yesterday, features the national teams from China, South Korea, Russia, Cuba, Brazil and Japan. Controversy rocked the tournament even before the first ball was struck with the organisers opting for a playing format which favours the Chinese team. Instead of splitting the two top qualifiers - Cuba and Brazil - into separate pools, officials insisted on seeding China No 1 and put them into the same group with Russia and South Korea. Cuba and Brazil, therefore, have to be in the same pool with Japan.
