TEENAGE players dominated the popular Coca-Cola/South China Tennis Open with John Hui Kin-yip and Willy Chan Lee walking off with the men's and women's championships. Seventeen-year-old John underlined his potential as one of the most exciting local players ever as he swept the $16,000 winner's cheque without dropping a set. He defeated Lee Kwok-chung, Paul Bailey, Franklin Demonteverde and Graeme Foster on his way to the final against fellow-teenager and Davis Cup teammate Melvin Tong Man-chung. Fifth-seeded John showed his class in the final as he dominated the match with his aggressive serve-and-volley game to hand 19-year-old Melvin a 6-2, 6-1 drubbing. The women's final was also a clash of two teenagers, with 18-year-old Willy giving 17-year-old Jacklyn Fu Yan-ning a tennis lesson with a convincing 6-1, 6-1 victory. Willy capitalised on her wider experience and steady base line game to control Jacklyn as she romped to her fourth Coca-Cola/South China crown in five years. Meanwhile, John will have a chance to test his mettle against five aspiring young professionals in the Stars of Tomorrow competition at the Marlboro Championships to be held this week. John is the only local player invited for the singles event. He has been drawn in the Germini group with South Korea's Lee Jong-min and American Scott Humphries. The other preliminary group, Aquarius, features Britain's Martin Lee, American Magnus Norman and Indian Davis Cup player Mahesh Bhupathi.
