HONG Kong's quest for a place in the Davis Cup elite division led to a popular call for non-playing captain Michael Walker to return as a player for this month's home tie against Indonesia. Walker, who was confirmed in a four-man squad yesterday, decided in December to give up playing and concentrate on coaching and development, leading to his appointment as non-playing captain over veteran Mark Bailey. But after Sven Koehler and Bill Young made themselves unavailable to play, and with the knowledge that Hong Kong stand only two wins away from taking on the likes of Sweden, Germany and the United States in the World Group, Walker was lured back as a player. Former team manager David Ho Wai-tak takes over as non-playing captain while Walker replaces Colin Grant as the number one singles player. Melvin Tong and Thorsten Poelzl complete the squad. Should Hong Kong beat a strong Indonesian team at Victoria Park, from March 25-27, they will then play Korea in the second round, with the winners entering the World Group qualifying rounds. The association's executive secretary Janet Hardisty said: ''The players feel they have a good chance of beating Indonesia with Mike in the squad. ''Colin, especially, was very keen to see Mike playing and was more than willing to drop down to number two. It would have been different if we didn't think we had a chance. But we do feel like we should make a big effort to get to the World Group.'' Indonesia, however, will pose a major threat with all four players holding a world ranking. None of the Hong Kong players are ranked on the senior circuit. Benny Wijaya, ranked 297, is joined by Bonit Wiryawan (554), Suwandi (845) and Donny Susetyo (842). Wijaya is one of the top players in Asia, reaching the semi-finals of December's Asian Championships in Hong Kong. Ho and Poelzl yesterday left Hong Kong to join the rest of the squad in Manila, where they are taking on Philippines Davis Cup squad in a series of training matches.
