Michael Chang will use an alien approach in a valiant bid to overcome the gremlins that have crept into his game these days. The Hong Kong favourite says he will rely on his new game plan when he meets fourth seed Alex Corretja of Spain in a mouthwatering first-round clash at the US$400,000 Salem Open today. Unseeded Chang, who received a wild card to appear for the 12th successive year, is likely to forsake his beloved baseline approach and instead change to a serve-and-volley game against his fancied opponent, who is ranked 100 places above him in the world order. 'Yes, I will play more aggressively,' answered Chang when asked if he would adopt the serve-and-volley style which he first unveiled at the US Open this month. The American, ranked 120 in the world, will be hoping this approach will be enough to jump-start his brave campaign to win a fourth Hong Kong title, in what he said could be his last appearance in the Salem Open, and also stay alive in the increasingly competitive world on the men's professional tour. 'I'm trying to mix things up and do something different. I feel if I don't change something, then the results are not going to come and continue the way that they have,' said Chang soon after his first-round victory over Francisco Clavet of Spain at the US Open. That he lost to Roger Federer in the next round had more to do with the fact that the Swiss star was ranked 11 and a hot favourite to win . . . a scenario Chang faces again today coming up against the world number 20. The 28-year-old Corretja, who is playing in Hong Kong for the first time, is well aware that Chang will be the sentimental favourite and is certain to give a 110 per cent in front of his 'home' fans tonight. Organisers have cleverly scheduled the match for 'prime time' at 7.30pm on centre court. 'I know that he is a favourite here in Hong Kong,' said Corretja after attending the opening lion dance ceremony yesterday. 'He has won here three times and I think it is about time he let the other guys win.' A two-time French Open finalist, Corretja showed his lighter side when asked how he felt coming up against Chang, saying: 'I hope it will be his last match.' Turning serious, Corretja then warned: 'I'm not going to make things easy for him.' The Barcelona native has played Chang on two previous occasions and lost both times. But the last defeat was more than two years ago, when Chang was a different player. Now in the twilight of his career, Chang is not going to give up without a fight. That's in his spirit, seen so early in his career, when he scored his most famous triumph at the 1989 French Open, his one and only Grand Slam title. Chang changed tactics at the US Open and caught everyone by surprise. It was in the middle of the first set when Jim Courier, a commentator on one of the US networks, noticed that Chang had approached the net 17 times, prompting him to say: 'Michael would go tournaments without approaching the net in the early '90s.' His co-commentator, the irrepressible John McEnroe, added: 'What's wrong with him? Take his temperature!' Chang came to the net 85 times against Clavet, winning 58 points. Obviously the novel approach worked. Tonight will be the first time he is in action since the US Open. Corretja, meanwhile, is relaxed and looking forward to his first taste of playing in Hong Kong. With countrymen Juan Carlos Ferrero and Carlos Moya, he enjoyed yesterday's noisy but colourful ceremony involving 10 lions. With a number of players still to arrive in Hong Kong due to Davis Cup commitments, organisers scheduled only one singles match yesterday, in which Korean Lee Hyung-taik beat Julian Knowle of Austria 7-5, 4-6, 6-1. The focus was mainly on the qualifying competition. The lucky four to progress after three qualifying rounds were Japan's Takao Suzuki, American Jeff Morrison, Swede Magnus Larsson and Germany's Michael Kohlmann. They will be entered in the 32-strong main draw.
