Defending champions England and a buoyant Fiji side on Friday both cruised through to the quarter-finals of the IRB World Sevens Series here. But there was no place in the Cup quarter-finals for Samoa, who lost out on points difference to Argentina. A Joeli Lutumailagi hat-trick powered the Fijians to a 31-14 win over Samoa in their final pool match to set up a quarter-final against Australia. James Brown, Osea Kolinisau and Pio Tuwai also scored for the Fijians in an ill-tempered match that saw two red cards after a high tackle from Sitiveni Waqa was followed by punching from Uale Mai. ut it was not enough for the Samoans, who saw Argentina\'s 73-7 rout of debutants the United Arab Emirates count as enough to put the Pumas through at their expense. Two second-half tries from Richard Smith and a late effort from Tob Habberfield helped Wales to a comprehensive 33-14 win over Australia to finish the day unbeaten. The win meant the Welsh topped Pool D ahead of the Australians, having also snuck past Scotland (14-7) and Canada (15-12), with a quarter-final clash against Argentina set for Saturday. South Africa sprung a surprise on New Zealand, defending series champions and nine-time winners out of the last 12 seasons on the international sevens circuit. The Springboks notched up a 21-5 win in a game in which the Kiwis were badly outmuscled in the tackle and breakdown. Kyle Brown rode a poor tackle from New Zealand captain DJ Forbes to open the scoring, and a beautiful offload from Boom Prinsloo saw Robert Eberhsohn go in to take the Africans to a 14-0 half-time lead. Forbes brought his team back into contention with an early second-half try, but William Small-Smith hit back with a well-taken five-pointer for a decisive win and a quarter against France. In their deciding Pool C match, the French clocked up the first points on the scoreboard against England after Manoel Dall\'Igna made the most of a clever Mathieu Acebes offload and some poor defence. Mat Turner got one back almost straight away and Dan Norton got a second after a strong run by the Fiji-born Isoa Damudamu. But France did not take it lying down and inspirational playmaker Terry Bouhraoua sped through for a converted try to equalise the scores at 12-12 at half-time. Norton, however, skinned Bouhraoua for an England lead, and a turnover in the red zone saw the speedster complete his hat-trick after good work from Rob Vickerman. Nick Royle added another try to seal a 29-12 victory to set up a tricky last eight match against New Zealand. Click here to find out more!
