Loh took the lead again at 12-9 before the Indian shuttler equalised at 16-16 before surging to a 21-18 victory. The trend continued in the second game and though Prannoy caught up with Loh at 13-13, the Singapore shuttler did not allow him more chances and grabbed the remaining points to win the second game 21-15. Prannoy raced to a 4-0 lead in the decider and though Loh brought it down to 4-3, the 31-year-old World No.9 won consecutive points to open a 9-3 lead and extended it to 11-4. The 2021 World Champion Loh launched another comeback and reduced the gap to 11-10 but Prannoy won the next four points.
