SINGAPORE - The third day of the Fina World Junior Swimming Championships saw another world junior record broken at the OCBC Aquatic Centre on Thursday.

The United States' Michael Andrew, who has broken 78 National Age Group Records - the most in USA Swimming history - completed the men's 50m backstroke in a meet record of 25.14 seconds to head into the semi-finals. The previous record of 25.44s was set by Russia's Grigory Tarasevich in 2013.

Meanwhile, Hoong En Qi became the first Singaporean swimmer to qualify for the semi-final, after clocking 27.59s in the women's 50m butterfly heats to finish 16th overall.

Also in action in the morning heats for Team Singapore were Nicholle Toh (women's 50m butterfly and 100m breaststroke), Kevin Ong, Francis Fong (men's 50m backstroke), Kathlyn Laiu (women's 100m breaststroke), Darren Lim, Teong Tzen Wei (men's 50m freestyle), Tan Jing-E, Hannah Quek (women's 200m backstroke), Darren Lim, Darren Chua, Tan Lee Shuen, Natasha Ong (mixed 4x100m Freestyle )

They did not make the semi-finals or final. Only the top 16 swimmers qualify for the semis, and the top-eight of the heats for the 400m events will progress into the final.

The evening session starts at 6pm and will feature nine races, including four finals - the women's 200m backstroke and 100m freestyle relay, the men's 100m butterfly and the mixed 4X100m medley.
