TAIPEI: Li Zhe and Zhang Zhizhen won singles rubbers Sunday to complete a 5-0 triumph for China over Taiwan in the Davis Cup Asia/Oceania Group I tie. Li beat Lee Kuan-yi 5-7, 6-2, 7-6 (7/3) while Zhang defeated Peng Hsien-yin (TPE) 6-2, 3-6, 7-6(7/4) in Kaohsiung city, although China has already sealed its victory following Saturday’s doubles rubber. Chinese pair Wu Di and Zhang Zhizhen took three straight sets from Jason Jung and Peng Hsien-yin 7-6 (7/4), 6-4, 6-3, putting China through to face Kazakhstan in a promotion play-off in early April. Taiwan has not beaten China in almost a decade, having lost the last three times the cross-strait opponents faced off in 2011, 2012, and 2013.
