Ratchanok battles, Zwiebler knocked out

Top seed Ratchanok Intanon had to work very hard for her victory over Sayaka Takahashi at the Thailand Open in Bangkok on Thursday, while men’s second seed Marc Zweibler was knocked out.

The former world number one gave her home fans at the Nimibutr Stadium a scare after dropping the second game against Takahashi, but she was able to bounce back to secure a 24-22, 10-21, 21-18 victory and book her place in the quarter-finals.

She moves on to face countrywoman and fifth seed Natchaon Jindapol.

Second seed Saina Nehwal also stayed on course after beating American Ying Ying Lee 21-11, 21-14.

Others to advance on the day included third seed Beiwen Zhang and fourth seed Busanan Ongbamrungphan.

In the men’s singles, German second seed Zwiebler suffered a surprise 22-20, 21-9 defeat at the hands of Malaysia’s Joo Ven Soong.

Top seed and local favourite Tanongsak Saensomboonsuk avoided a similar fate by dispatching countryman Suppanyu Avihingsanon 21-9, 21-8.

Third seed B. Sai Praneeth also advanced to the quarter-finals, as did Jonatan Christie and Brice Leverdez, the fourth and fifth seeds.
