Quah Zheng Wen set a new national record in the men's 100m backstroke at the world swimming championships in Kazan, Russia, yesterday.
The 18-year-old clocked 54.40 seconds in the heats to erase his old mark of 54.51, finishing 21st in a field of 67 swimmers.
He did not qualify for last night's semi-finals.
The lanky swimmer missed out narrowly on the event's Olympic 'A' qualifying time of 54.36, which would have guaranteed him a spot in the Rio Games next year.
He has already made the 'A' cut in the 200m butterfly.
Quah's teammates Danny Yeo and Rachel Tseng were also in action yesterday.
Yeo, 25, clocked 1min 51.29sec to finish 49th in the men's 200m freestyle, while Rachel, 17, posted 17:26.53 to finish 23rd in the women's 1,500m freestyle.
Both failed to progress beyond the heats.
