HONG Kong's two leading under-16 tennis stars - John Hui and Jacklyn Fu - will be heading for the US in December for the world's premier junior tournament. The talented duo's recent performance in major junior international events in Brunei and Darwin, Australia, prompted coach Geoff Masters to consider entering them for the Orange Bowl. Hui, 15, came within a whisker of being the territory's first junior to win an International Tennis Federation (ITF) tournament when he was narrowly beaten in the Darwin final. The strongly-built Hong Kong International School student pushed Australia's Novak Nash to three sets before going down 7-5, 3-6, 7-6. His achievement saw him shooting up to 230 in the world ranking for under-18 players. He is 11th for under-16-year-olds. Fu, who turned 15 on Monday, also did remarkably well despite facing older and more experienced opposition in the two overseas events. She reached the quarter-finals in Brunei and made the last 16 in Darwin. The Island School student is now ranked 370 on the ITF junior women's chart and despite her tender years, she is among the top 20 under-16s.
