England and New Zealand also won all three of their matches Saturday to top their pools and reach the quarterfinals. England edged Australia 24-21, adding to comfortable wins over Spain and Scotland and will next face Canada. New Zealand beat Portugal, Wales and Canada and will face Australia on Sunday. The other quarterfinal match-up is Fiji against Kenya. Force upsets Chiefs Two tries from captain Matt Hodgson laid the platform for the Western Force as it upset defending champions Waikato Chiefs 18-15 in Perth to end their 100 percent Super Rugby record this season. Hodgson scored his first after 13 minutes as the Force stormed over the Chiefs' defence from a lineout, and again six minutes into the second half with a pick-up from close range. The Chiefs, who had won their three previous games this season, were unable to convert late pressure into a score and had to rely on the boots of Aaron Cruden and Gareth Ainscombe for their points, all coming from penalties. Sias Ebersohn kicked two penalties and a conversion as Western Force won for a third successive game. Brumbies beat Stormers In Canberra, winger Robbie Coleman scored a try in each half before a late penalty try clinched the ACT Brumbies' 25-15 win over the Cape Town-based Stormers in Super Rugby Saturday. Coleman's try in the eighth minute helped the Brumbies to a 13-10 lead at halftime and his second in the 62nd minute, almost miraculously achieved from a cross-kick by captain Ben Mowen, boosted them to their fourth win from five games. Juan de Jongh scored a late try for the Stormers, cutting the Brumbies' lead to 18-15 but prolific flyhalf Peter Grant missed the conversion and an earlier penalty before a penalty try from the scrum hoisted the Brumbies to a flattering 10-point margin. Blues down Cheetahs In Auckland, the Auckland-based Blues beat South Africa's Cheetahs 40-30 in Super Rugby in a match decided by a refereeing decision that appeared to be lost in translation. The Blues were leading 16-13 when center George Moala stretched for the goal line in the 29th minute after his bid to score initially appeared to have been stopped short. Argentina referee Francisco Pastrana referred the decision on the try to New Zealand television referee Glenn Newman, asking whether a double movement had occurred. Newman responded with a long, technical reply which indicated the try should be disallowed, but Pastrana struggled to understand him and mistakenly awarded the try to the Blues. — Agencies
