Hong Kong pulled off one of the biggest upsets in the history of World Sevens Saturday with a last-gasp victory against world champion Wales. Meanwhile it was business as usual for emerging favorite New Zealand and Fiji as a lacklustre Samoa, widely tipped to win at the start of the tournament, showed it has room for improvement. The host of the showpiece Hong Kong Sevens sent a rapidly-filling 40,000 capacity stadium wild as Anthony Haynes crossed for a converted try to give the underdogs a 21-19 win described by their Welsh coach Dai Rees as a career high. The fairytale ended as it limped out 40-7 loser to Japan. Organizers hope the world-renowned Hong Kong Sevens will reinforce interest in the sport ahead of its Olympic debut in Brazil in 2016. New Zealand enjoyed an emphatic 36-0 win over France with two tries each from DJ Forbes and Zar Lawrence and proved it had resilience as well as flair with a hard-fought 22-5 win against a spritely Scotland. Portugal looked like it was there to make up the numbers as Fiji demolished it 45-7 but was a different side when it beat Thailand 50-0. Fiji, meanwhile, staked its own claim as the team to beat when it followed its win over Portugal with a convincing 38-12 victory over the USA. The up-and-coming Americans had earlier shown the kind of form that saw them reach the final of the Adelaide leg of the series, with a blistering 62-0 demolition of Thailand. England impressed with a 45-0 win over Japan. Argentine Joaquin Tuculet looked equally impressive as the Pumas trounced Italy 42-0. South Africa underlined its threat with a 40-7 victory over Korea before beating Kenya while Australia went from strength to strength with easy wins over Tonga and Canada. Samoa maintained its perfect record but failed to impress in either of Saturday's outings, beating Russia 24-12 and then eking out a labored 21-14 win over Argentina to qualify for Sunday's semifinals. Bulls stay unbeaten The Bulls remain Super 14 rugby's only unbeaten side after winning 28-15 against the last-place Western Force, who proved tougher than expected in Perth Saturday. Lachie Turner dashed 95m for a 71st-minute intercept try, clinching a 39-32 win for the NSW Waratahs over the Auckland Blues in Sydney. In Wellington, Springboks scrumhalf Ruan Pienaar kicked a penalty after the fulltime siren to lift South Africa's Sharks to a 29-26 win over the Wellington Hurricanes.
