Winning is the best medicine to ward off ill thoughts of retirement. Hong Kong veteran Melvin Tong who had harboured sentiments of stepping down from Davis Cup competition kept his options open after partnering John Hui to victory over Malaysia in the doubles to wrap up the Asia/Oceania Zone Group II play-off tie at Victoria Park yesterday. Hui and Tong came back from an early lapse to beat Malaysia's Si Yew-ming and Adam Jaya 3-6, 6-4, 7-6 (7-3), 6-3. Having won both opening singles on Friday, Hong Kong finished off the tie, 3-0, to avoid relegation to Group III, a fate that awaits Malaysia next year. Immediately after the victory celebrations, all eyes were on Tong who had said earlier he might retire after this year's Davis Cup campaign. But in the glow of victory, Tong said he would have to think about throwing in the towel. 'I don't know at the moment if this will be my last Davis Cup campaign. It depends on a lot of things. Like what my captain thinks. I can't say for sure whether I will continue or not,' said Tong, a veteran of eight years. Flashes of brilliance late in the match yesterday proved Tong still has much to contribute - if he puts his mind to it. Having trailed Malaysia in the first three sets, before winning the second and third at the death, Hong Kong for the first time put their noses in front from the outset in the fourth set, leading two sets to one and 1-0 up. With the pressure off, Tong came into his own and announced it to one and all with a sizzling cross-court forehand return off Si's serve. That shot seemed to surprise even Tong himself. Then he won the next point with another blistering forehand down the line. With Tong on fire, Hong Kong broke through early and rushed to a 3-0 lead that they soon extended to 5-2. The end was in sight and Hui duly served out the match, finishing it off with an ace. Captain Derek Ling afterwards paid tribute to Tong. 'After Melvin won the bronze medal at the China National Games last year along with John, he said he was thinking of retiring. But he is only 27 and I feel he still has a lot to offer,' he said. In the flush of victory, the picture seems rosy. But what Ling and Hong Kong will have to remember is that nothing less than victory was required. Early in the day, it seemed as if Malaysia would set the stage for a Sunday showdown by winning the doubles. Hui and Tong could not find the juice in the tank in the first set as they collapsed in the face of an on-fire Malaysian duo who engineered eight break points and converted two of them, in the first and ninth games to take the first set 6-3. In answer, Hong Kong could not even manufacture a single break point. 'We started a bit sluggish today. But we came back well,' said Hui. They certainly did. Hong Kong leveled the score after Hui held his nerve while serving for the set at 5-4. He double-faulted on set point. But he kept his composure as Hong Kong saved two break points before converting their second set-point to make it one set each. Hong Kong fell behind again in the third set, trailing 5-2. To make it worse, Hui received a code violation for throwing his racquet, more in disgust with himself than anything else. 'That woke me up,' he said later. It certainly seemed to motivate him as he and Tong fought back superbly, winning the next three games to make it 5-5. The set went to a tie-break and the more experienced Hong Kong duo prevailed easily. The fourth set was all Hong Kong with Tong also on fire by now. 'I'm very relieved. We could have easily lost that one. And tomorrow could have been anybody's game,' Ling said. But he can afford to relax today. The plan is to allow Hui to continue his singles renaissance and play in the first reverse singles. Then Hong Kong will blood teenager Yu Hiu-tung, who at 17 represents the future of Hong Kong. Watching from the stands will be Tong - who could soon be just a part of the history of Hong Kong's Davis Cup tennis.
