SINGAPORE - National shooter Jasmine Ser beat the odds on Sunday when she earned a spot at the upcoming Olympic Games after finishing first in a women's 50m three-positions event.

The 25-year-old, competing at the Asian qualifying event in New Delhi, had qualified first with a score of 586 in the preliminaries. She was competing for one of three spots available, in her last shot at earning a ticket to the Rio Games in August.

Iran's Mahlagha Jambozorg and South Korean Lee Kye Rim earned the other two spots.

Ser, who had been struck with a bad case of food poisoning after arriving in India, had on Friday missed out in the 10m air rifle event although she made the final. The Singaporean, like several of her team-mates, fell ill and even had to go to a hospital to be put on intravenous drip.

The Rio Games will be Ser's second Olympics. She competed at the London Games on an unused quota place.

Air pistol shooter Teo Shun Xie also earned a ticket to the Games when she finished sixth in the women's 25m air pistol event. Three spots were up for grabs but South Korea, which swept the podium, could only earn one as the team had already taken up one quota place at an earlier qualification event. Japan's Akiko Sato, in fourth place, earned the second slot. Chinese Taipei's Wu Chia-ying, who was fifth, had also earned a berth at an earlier event.

This will be Teo's first Olympics and the first time since the 1964 Games that Singapore will be represented by two shooters at the quadrennial event.
