Dubai Rugby 7s: England, SA, Fiji and NZ all top pools

England, South Africa, Fiji and New Zealand all topped their pools with three out of three wins in the opening leg of the Sevens world series.

England, the series runner-up last season, downed Scotland 29-0 with four Dan Norton tries to top Pool B.

Norton, the Sevens' specialist, proved impossible to mark and his pace was too much to handle for a Scotland side that progress after scrambling past France and Spain to line up a quarter-final with Fiji.

South Africa shook off some rust in beating Uganda 19-10 in the opener, then defeated Kenya 48-5 and blanked Canada, the winner in Singapore in April, by 28-0.

Fiji won the best match of the day in their 26-19 thriller with Australia to sweep Pool C.

The Australians scored in the first minute but Fiji replied and the contest went tit-for-tat to leave Fiji ahead 14-12 at half-time.

That rhythm continued into a cracking second-half as Australia scored first before Fiji levelled to leave the teams tied 21-21, before substitute John Stewart scored the winner for a 26-19 victory.

New Zealand had to dig deep in Pool D. The Kiwis beat Samoa 24-12, came from 19-7 down to edge Argentina 21-19 through a last-minute try by Sione Molia and eventually prevailed 22-12 over the United States.

The US, without Sevens' player of the year Perry Baker, lost all three pool matches and Samoa advanced as the runner-up.

England will play Australia on Saturday, South Africa play Samoa, while New Zealand face Kenya.

Meanwhile, Australia won the women's final beating the United States 34-0.
