Ng Tze Yong claimed another big scalp in his career after he knocked out top seed Chou Tien-chen 23-21, 23-21 to march into the Thailand Open quarter-finals on Thursday.

Just like his victory over Viktor Axelsen at the All England, this performance showcased the world number 24’s talents, as he battled to recover from big deficits in both games.

Ng trailed the Chinese Taipei star 9-17 in the first game, and even overcame a fault return in deuce to take the opening game.

The Malaysian stayed patient in the second game even as he trailed 10-15, doing well to keep the rallies going and force Chou into making mistakes.

His opponent soon grew edgy, and Ng sealed victory when Chou floated a shuttle too high at the net for an easy kill and to seal the glamorous victory.

Ng goes on to face either Lee Cheuk Yiu in the last eight.

Leong Jun Hao made it a successful day in the men’s singles when he beat Frenchman Christo Popov in a thrilling 20-22, 21-13, 21-19 victory.

That success pits him next against Lakshya Sen, who defeated Li Shi Feng.

However, there wasn’t any joy for the rest of the Malaysian contingent in action on Thursday.

All three mixed doubles pairs - Chen Tang Jie-Toh Ee Wei, Chan Peng Soon-Cheah Yee See and Goh Soon Huat-Shevon Lai - lost their respective matches.
