Lee Zii Jia is one game away from the German Open final after seeing off China’s Zhao Jun Peng 21-12, 21-18 on Friday to step into the semi-finals of the men’s singles.

Lee was previously taken to three games before prevailing against Mark Caljouw and Christo Popov, and he was up against an opponent who had won his first two matches with relative ease in straight games.

But there wasn’t any question about Lee's durability as he disposed of the fifth ranked Chinese in just 40 minutes.

The world number seven now goes on to face either Kunvalut Vitidsarn or Kenta Nishimoto for a place in the final.

Lee’s path looked to have been made easier by the exits of Kento Momota and Jonatan Christie at the hands of Kunvalut and Nishimoto, but the Malaysian would not be taking either shuttler for granted after their dominant victories over their fancied opponents.

Vivian Hoo-Lim Chiew Sien’s run meanwhile came to an end after they lost 15-21, 20-22 to top seeds Chen Qing Chen-Jia Yi Fan in the women's doubles.

Besides Momota and Christie, Tai Tzu Ying and Akane Yamaguchi were the other top names in the women’s singles who exited early, while Thailand's Ratchanok Intanon had to withdraw after testing positive for COVID-19.
