Athletics: Shanti Pereira clocks 11.96sec in 100m s-finals at World Youth Championships

National sprinter Shanti Pereira clocked 11.96sec in the women's 100m semi-finals of the ongoing International Association of Athletics Federations World Youth Championships on Thursday night, finishing fourth out of eight runners in her semi-final.

The 16-year-old became the new holder of the women's national 100m mark on Wednesday, posting 11.89 to eclipse Amanda Choo's 12.01 set in 2010.

Her performance was not just a new national mark, but were also new records in the national Under-23, national junior, youth and Under-19 categories, pending ratification by the Singapore Athletic Association.

Meanwhile, Ang Ding Hui clocked 14.42 in the men's 110m hurdles to finish seventh in his heat. It is a season's best for the 17-year-old.

At the World University Games in Kazan, Russia, the national men's 4x100m relay team clocked 40.15 in their heats to qualify last for the final on Friday.

It will be the squad's last chance at qualifying for the athletics world championships in Moscow next month. They need to meet the qualifying mark of 39.20 to earn a berth at the world championships.
