SINGAPORE - The Singapore national men's and women's rugby sevens teams both booked their spots in the inaugural Southeast Asia Sevens finals, after a day of non-stop action on a sweltering Friday at Yio Chu Kang Stadium.

The men's team eased past their Group B opponents, beating Indonesia (45-0), Laos (31-0) and Brunei (47-0) to finish top of the group. They will face Group A winners Thailand in the final.

The ladies had a tougher route to the final, having lost 5-29 to Thailand in their opening match. But a subsequent 28-7 win over Laos meant they finished second to face Group A winners, the Philippines, in the semi-final.

Stepping it up a gear, tries from centre Lai Pui San and scrum-half Eunice Chu earned them a 12-5 win and a berth in the final, where they have the chance to make amends against main rivals Thailand.

The men's developmental team, named the Singapore A team, displayed glimpses of potential, but ultimately lost all three games in a tough group A comprising regional powerhouses the Philippines, Malaysia and Thailand.

They eventually finished overall seventh out of eight teams after a 28-0 win over Indonesia in the seventh/eighth position play-off.

The women's final will start at 12:56pm at the National Stadium on Saturday, after match eight of the HSBC Singapore Rugby Sevens between England and Portugal, while the men's final will begin at 16:17pm, after match 16 between England and Samoa.
