SINGAPORE — Rising stars Kang Khai Xing-Aaron Tai produced a stunning upset at the Singapore Open badminton championships yesterday to join two other national men’s doubles pairs — defending champions Aaron Chia-Soh Wooi Yik and former world number one Goh Sze Fei-Nur Izzuddin Mohd Rumsani — in the quarter-finals.

World No 23 Khai Xing-Aaron, competing in only their second Super 750 tournament, stunned world No 7 Sabar Karyaman Gutama-Moh Reza Pahlevi Isfahani of Indonesia 21-19, 21-17 in 38 minutes in their second-round match at the Singapore Indoor Stadium.

On Tuesday, the young Malaysian pair overcame their world No 23 compatriots Nur Azriyn Ayub-Tan Wee Kiong 21-15, 21-17 in the opening round.

Khai Xing-Aaron will face India’s Chirag Shetty-Satwiksairaj Rankireddy in the last eight.

World No 2 Aaron-Wooi Yik, meanwhile, needed 43 minutes to subdue England’s Ben Lane-Sean Vendy 21-18, 21-16 to check into the quarter-finals.

Aaron-Wooi Yik, however, can expect a torrid time in the last eight as they will be up against China’s world No 5 Liang Weikeng-Wang Chang.

Sze Fei-Nur Izzuddin had a tough time against compatriots Junaidi Arif-Yap Roy King in their second-round clash before prevailing 23-21, 16-21, 21-8 in 52 minutes.

Sze Fei-Nur Izzuddin will have their work cut out for them as they will meet Indonesia’s world No 3 Fajar Alfian-Muhammad Shohibul Fikri in the last eight.
