CHINA completed a whitewash of Team America in their six-game basketball series with a 115-104 victory at the Hongkong Coliseum last night - but the American side's player-coach Tom McCarthy promised there would be no such rout in next year's challenge. McCarthy admitted he had underestimated the Chinese when he selected his squad of sometime NBA and CBA stars, most of whom are past their prime. ''At the beginning of the tour I thought it would be easy for us but after the opening defeat in Beijing I knew we were in trouble,'' said McCarthy, who made a brief appearance in the third quarter. ''Next year I'll get a younger team and try to have a bit more co-ordination in our preparation,'' he added, referring to the lack of practice since the players assembled for the tour in late May. The Americans were boosted by the last-minute call-up of Wallace Bryant, a seven-foot giant playing in the Super Commercial Cup for Burlingame. But the Chinese, a revamped outfit following six changes after a bad Barcelona Olympics last year, showed far superior teamwork as they stormed to a 29-18 lead in the opening 12-minute quarter. With guard Adiljan capturing the admiration of the paltry 1,500 crowd at the 11,000-seat arena with his excellent ball control and clever distribution, China pulled away to a commanding 61-38 lead at half-time. They extended their advantage by another point in the third quarter. Only when China took their foot off the gas did the Americans close the deficit to 94-83 five minutes into the final period. The closest they got was in the last minute when Ricky Wilson netted two baskets, reducing the difference to 109-100. Veteran Wu Qinglong top-scored for the Chinese with 25 points while Zheng Wu, a newcomer to the national squad, had 17 points. Scoring honours for the match went to Team America's Wayne Casey with 30 points. Chinese coach Jiang Xingquan was delighted with his team's 6-0 shut-out of the Americans and is confident about the World University Games in Buffalo, United States, next month. ''This is the tallest Chinese team we have ever had with an average height of 1.98 metres and most of the players are very young. I think there is still room for improvement,'' Jiang said. ''The Team America players have excellent individual skills and we've learned a lot from them.''
