Quah Zheng Wen rewrote his own national record in the 100m backstroke on Friday evening with a swim of 56.60sec at the Singapore National Swimming Championships.

The 16-year-old finished behind China's Yan Jin (56.33) but still bettered his previous mark of 56.63, set last year.

It was a satisfying evening for the Republic's swim queen Tao Li as well, as she raced to victories in the 100m backstroke and 100m butterfly events.

Lynette Lim's time of 8min 57.16sec in the 800m freestyle, meanwhile, booked her a spot at December's SEA Games in Myanmar.
