China have won their Davis Cup tie against New Zealand 3-1 in Tianjin after No.1 Rubin Statham was beaten 1-6 6-3 6-4 by Yibing Wu in Tianjin.
Statham took an early lead, racing through it 6-1 with two breaks of serve and playing with real intensity.
But the 18-year-old Wu, who won the US Open boys title in September, found his range and rhythm in taking the next two sets 6-3 6-4 to wrap up the Asia Oceania group one tie in a shade over two hours.
The victory clinched the tie for China, who took a 2-1 lead when Ze Zhang and Mao Xin Gong upset Marcus Daniell and Artem Sitak 6-4 6-4 in the doubles rubber.
China will go on to play India in April for a place in September's World Group qualifying round.
While New Zealand captain Alistair Hunt was disappointed with the result, he couldn't fault his players' effort.
"Rubin played two of the best Davis Cup matches I have ever seen him play, he had chances today against a brilliant young player and the match could have gone either way," Hunt said.
Daniell and Sitak were guilty of serving a staggering 10 double faults between them and had a first serve percentage of just 56 per cent compared to 74 per cent for their opponents.
Zhang and Gong were able to convert two of their four break point chances, while Daniell and Sitak only managed one break point off the Chinese players serves in the entire match.
Hunt admitted Daniell and Sitak didn't play their best tennis.
"I think for them the new format didn't help because they were getting into the match in the second set and then it was over.
"If it has been best of five I would have backed them.
"They had won eight or nine matches in a row for New Zealand and unfortunately today they came up a bit short."
The defeat means New Zealand will almost certainly face a trip to South Korea later this year for a relegation tie, with the Koreans trailing Pakistan 2-0 in Islamabad heading into the doubles rubber.
