A total of 16 swimmers have met qualifying marks for next June by the end of the Singapore National Swimming Championships (SNSC) on Sunday night, with several meet records tumbling on the last day of the meet.

The SNSC is one of three qualifying events for the June 5-16 SEA Games on home soil next year, with the other two a time trials in February and the National Age Group Championships in March. The top two swimmers from each event by the end of the qualifying window will represent Singapore at the biennial Games.

Rachel Tseng led the way with breaking records at the OCBC Aquatic Centre on Sunday with the first event of the night, clocking 17min 8min 5sec in the women's 1,500m freestyle event to eclipse the 2006 mark of 17:30.59 set by Quah Ting Wen.

Clement Lim then clocked an unexpected result in the men's 50m breaststroke, posting a 28.54sec to re-write Lionel Khoo's 2012 mark of 28.90. The timing was also good enough to qualify for the SEA Games next June.

Quah Zheng Wen then smashed his own record in the men's 50m backstroke, clocking 25.82s to eclipse his previous time of 26.35 set last year. It was also under the qualifying mark for the SEA Games.

Pang Sheng Jun also posted a new meet record in the men's 400m freestyle. He clocked 3:58.73 to break Danny Yeo's 2010 time of 4:00.14, also meeting the SEA Games requirement in the process.

With the exception of Rachel, who represents Aquatic Performance Swim Club, all the record breakers are from Swimfast Aquatic Club.

The Quah siblings were also named the event's most valuable male and female swimmers.

Meanwhile, Amanda Lim and Quah Ting Wen also met the SEA Games qualifying marks for the women's 50m freestyle. Lim won the event with a 25.66s effort, while Quah clocked 25.68s. Quah also met the 100m butterfly event SEA Games qualifying mark with a 1:00.43.
