QUAH Ting Wen broke a third national record at the National Swimming Championships on Sunday, clocking 25.65sec in the 50m freestyle.

She erased her own national and Under-17 mark of 25.80sec, set in March.

Second-placed Amanda Lim, 16, also improved on that mark, finishing in 25.75sec.

Both the Asian Youth Games-bound swimmers met the South-east Asia Games 'A' qualifying mark of 26.80sec.

Ting Wen had re-written her own national marks in the 100m and 200m freestyle events earlier during the five-day meet, which ended on Sunday at the Singapore Sports School.

The Swimfast Aquatic Club (SAC) swimmer's feats earned her the accolade of Best Female Swimmer. She also clinched the Kee Soon Bee Cup, awarded to the 400m freestyle champion.

SAC made a clean sweep of the trophies at the meet.

Nicholas Tan, 21, claimed the Neo Chwee Kok and Chan Ah Kow Cup, awarded to the winners of the 100m freestyle and 100m butterfly respectively.

SAC accumulated more than 2,000 points - more than double that of their closest competitors - to retain the challenge trophy with ease.

The Singapore Swimming Association is also expected to nominate the four fastest swimmers in the 200m freestyle event - Marcus Cheah, Joshua Lim, Danny Yeo and Nicholas Tan - for the relay event. All four met the 'B' qualifying mark of 1:54.73.
