Hong Kong's victorious Davis Cup squad will undergo special training before April's semi-final tie away to Indonesia - they will listen to loud rock music. 'We believe the crowds in Indonesia will be pretty hostile and loud, and to prepare our guys for that, we will train under noisy conditions, said non-playing captain Derek Ling. 'I will play tapes of music, of people cheering and clapping while they train.' Hong Kong beat Pacific Oceania 4-1 in the first round of the Asia/Oceania Zone group two tie last weekend to earn a semi-final clash against top seeds Indonesia. The tie, which is likely to be played in Jakarta from April 7-9 - Indonesia are yet to announce the venue and the surface - will be the first time that most of the current squad will be involved in Davis Cup overseas. 'It will be the first time for a couple of the guys to play Davis Cup overseas,' said Ling. 'Even the more senior guys like Wayne Wong or Yu Hiu-tung will not have experienced playing in front of such hostile crowds. The last time we played away was back in 2004 in the Philippines and before that in Sri Lanka. 'Indonesia will be totally different to anything these guys will have experienced and we need to be prepared. We will train under the noisiest conditions possible so that the guys can learn how to block out all the outside noise,' explained Ling. Wong and Yu spearheaded Hong Kong's victory over Pacific Oceania, playing in the singles, while Martin Sayer teamed with Wong in the doubles. Michael Lai was the fourth player and he figured in the last rubber with the SAR holding an unbeatable 3-1 lead. While the entire squad will be available for the next round, there is a question mark over Sayer, who has returned to the United States to continue his university studies. 'Martin is currently 17th in the American NCAA [college] rankings and we don't know if he will be available for us in April,' said Ling. 'It will depend on his tennis coach and also on his studies. Apart from Martin, we would also like to have Brian Hung with us for this crucial tie.' Hung, who was unavailable for the first-round tie, is also studying in the US and is the number one ranked player and captain of the University of Michigan team.
