Intro:

Singapore rule day one in the pool at the ASEAN Swimming Championships.

Script:

The opening night of the inaugural Southeast Asian Swimming Championships proved to be a golden one for Vietnamese teenager Nguyen Thi Anh Vien.

The 15-year-old started the evening by winning the women's 200-metre backstroke in 2 minutes 13.84 seconds.

She then added a second gold medal when she won the women's 200-metre individual medley in a time of 2 minutes 17.67 seconds.

With most Olympic qualified swimmers skipping the event, the field was wide open for the teenagers and Singaporean 15-year-old Mylene Ong took advantage, winning the gold in the women's 100-metre freestyle with a time of 56.02 seconds.

That put her under the Olympic invitational selection qualifying time of 56.48.

The Indonesia team picked up their first gold of the swimming competition when Sudartawa I Gede Siman touched out just ahead of fastest qualifier Zheng Wen Quah of Singapore to win the men's 200-metre backstroke in 2 minutes 03.07 seconds.

But Quah, who is yet another 15-year-old in the field, did pick up gold in the men's 400m individual medley with a winning time of 4:27.62.

It was another gold for hosts Singapore in the men's 50 metre breaststroke as Lionel Khoo proved the quickest in 28.75 seconds.
