Hong Kong will face a stiff battle when it fields a young and relatively untested squad against Pakistan in the opening round of the Davis Cup Asia/Oceania Zone Group Two match at Victoria Park on Friday. The unavailability of three leading players - Wayne Wong Wing-luen, Brian Hung Lap-hei and Martin Sayer - has forced Hong Kong Davis Cup captain Derek Ling Hay-ming to call up two juniors into his four-strong squad for the first-round tie. 'Both Wayne and Brian are unavailable due to work commitments, while Martin, who is in the United States, is still recovering from a wrist injury which he picked up during last year's China National Games,' Ling said yesterday. Hong Kong will have to rely on Yu Hiu-tung and Jack Hui Cheuk-wai to provide the experience and fire power to challenge favourites Pakistan, who will be led by veteran Aisam Ul-Haq Qureshi. Yu and Hui, who figured in the last Davis Cup tie, will be expected to play the singles matches. The two juniors are 16-year-old Kelvin Lam Siu-fai and 19-year-old Ray Lam Wing-lun, the reigning CRC junior champion. 'It's going to be a tough battle. We have never beaten Pakistan in Davis Cup action,' Ling said. 'The last time we met them was exactly 10 years ago when we lost 4-1 in an opening round match.' History is set to repeat itself with the Qureshi-led Pakistan appearing to hold the edge. The other players are Aqeel Khan, who was once ranked in the 300s on the ATP world list, and Jalil Khan and Yasir Khan. 'I don't know if these Khans are brothers or not, but I definitely know Qureshi and Aqeel Khan will pose problems. They are ranked a lot higher than any of our players and it is not going to be easy,' Ling said. Hong Kong have struggled to stay in Group Two for the last three years. In 2007 and 2008, they lost to Indonesia in the first round before defeating Iran and Lebanon in the relegation play-offs. Last year, the Philippines defeated Hong Kong in the opening tie before a win over Oman secured a lifeline. 'We have just been surviving in Group Two for the last three years. It is going to be difficult once again, but I'm confident we can do it,' Ling said.
