Four things to look out for

1 Can Shanti Pereira break the 12-sec barrier again?

The national 100m and 200m women's record holder is Singapore's biggest medal hope in the two sprint events. But since rewriting the 100m national mark with an 11.89 effort in 2013, the 18-year-old has struggled to clock similar times in the last six months. Her best time this year is 12.09 clocked in January.

But a good timing - and a gold medal today - would certainly be a fillip to her hopes of winning Singapore's first SEA Games medal in the women's sprints since 1973.

WHAT: Women's 100m final

WHEN: Today, from 2.45pm

2 Who will contest the men's 100m in June?

At the moment, Amirudin Jamal is the only Singaporean who has met the 10.55sec mark to qualify for the 100m event at June's SEA Games.

But he knows he cannot take the spot for granted. The likes of Gary Yeo, Calvin Kang, Elfi Mustapa and, even teenage upstart Naqib Asmin, 19, are also hoping to be among the two qualifiers.

The presence of Indonesia's Iswandi - the 2013 SEA Games silver medallist - adds further spice to the Singapore Open.

WHAT: Men's 100m final

WHEN: Today, from 2.45pm

3 Will vaulters leap to greater heights?

Pole vaulter Sean Lim became the first Singaporean to clear five metres last March, and his mark of 5.01m is still the national best.

Injury and university studies have hampered his preparations but Lim, 21, is targeting to clear 5m.

Women's record holder Rachel Yang, who bettered her own mark of 3.82m by 1cm last week, is hoping to shine at the new stadium.

WHAT: Pole vault final

WHEN: Tomorrow, 9am (women's) and 2pm (men's)

4 Can Dipna go from strength to strength?

Dipna Lim-Prasad rewrote her own national record in the 400m hurdles in Australia last month, shaving 0.10sec off her previous best which helped her win bronze at the 2013 SEA Games.

On a quality Mondo track at the Sports Hub and, with her rivals Wassana Winatho (Thailand) and Quach Thi Lan (Vietnam), who finished ahead of her in 2013, not taking part, the 23-year-old Lim-Prasad can consider herself a favourite at the Singapore Open.

WHAT: Women's 400m hurdles final

WHEN: Tomorrow, from 9.30am.
