BERLIN, Nov. 5 (Xinhua) -- China's Wen Ruibo upset compatriot Wang Chuqin in straight games in the men's singles round of 16 at WTT Champions Frankfurt on Thursday.
Wen defeated fourth seed Wang 11-7, 11-8, 11-6 in just 23 minutes and 37 seconds, ending Wang's first international tournament in more than a month.
Wang led 4-2 in the opening game and was still ahead at 7-6 before Wen reeled off five consecutive points to take the game.
Wen moved 4-1 ahead in the second and extended his advantage to 10-6. Wang saved two game points but could not prevent his younger teammate from taking a two-game lead.
In the third, Wang briefly led 2-1 before Wen pulled away. Wang narrowed the deficit to 8-6, only for Wen to win the final three points and seal his place in the quarterfinals.
Wang had missed the WTT China Smash and WTT Champions Montpellier before returning in Frankfurt, where he beat Denmark's Anders Lind 3-0 in Tuesday's opening round.
The 19-year-old Wen, who had also beaten South Korea's An Jae-hyun in straight games in the first round, will next face either compatriot Zhou Qihao or Lin Yun-ju of Chinese Taipei.
