Victory over Iran has created a problem for Hong Kong Davis Cup captain Derek Ling. With less then eight weeks to go before the SAR's second-round tie against Lebanon he has to find a suitable training venue for his squad - one made of clay. It is expected that the Lebanese, who will host Hong Kong from April 6-8 in Beirut, will prefer to play on clay, the most common surface in the Middle East. 'There are no clay courts in Hong Kong and that will be an obstacle to our preparation. I hope I get the budget to allow the squad to train on clay,' said Ling after Hong Kong had completed a clean sweep over Iran yesterday. Having wrapped up the tie on Saturday, both the reverse singles were of academic interest and Iran used the opportunity to give the lesser lights in their squad a chance to shine. John Hui, who featured prominently in the doubles victory with Michael Brown, played the first reverse singles while Wayne Wong played the second for Hong Kong. Hui lost to Hassani Nafez 7-5, 6-3 while Wayne Wong beat Akbar Rahaghi 6-3, 7-5 to give Hong Kong a 4-1 triumph over Iran in the first-round Asia-Oceania Zone Group Two tie. But non-playing captain Ling was already thinking ahead to the date in Beirut. 'It is going to be tough as they will have the home-court advantage. They are also a good side as they were relegated from Group One last year. So we can expect a battle.' The silver lining to the possibility that the Lebanese will use clay courts is that Hong Kong has got a clay-court specialist in their midst - debutant Brown - who also proved to be a revelation in the doubles, even surprising Ling. 'Clay is my favourite surface. It suits my type of game perfectly and I love it. I have also played a lot of doubles in my ATP career,' said Brown, Hong Kong's saviour against Iran. While victory this weekend was a team effort, there can be no denying that the foundation was laid by Brown, an Australian who had only recently qualified to play under the Davis Cup's two-year residency rules. Hardcore tennis fans will not forget that the last time Hong Kong were in the company of the elite in Asia - Group One, which is the holy grail for this team - it was in 1995 when the team featured names like Thorsten Poelzl and Sven Kohler. Before that it was carried on the shoulders of players like Mark Bailey, Colin Grant and Mike Walker. The past five years have been lean and it is no coincidence that the teams have relied mostly on homegrown players - until this weekend when Brown turned up. The significance of his presence has not been lost on Ling. 'He has been a blessing,' said Ling after Hong Kong clinched the doubles on Saturday. Cannily, Ling did not use Brown yesterday in the reverse singles. Having achieved the target, why continue with Brown and alienate sections of the tennis community who support localisation? Why not let the locals gain some experience. So it was left to Hui and Wong to carry the flag yesterday. And Wong did it with aplomb, finishing the tie with a hundred per cent win record. As did Brown.
