AUCKLAND (Reuters) - A huge defensive effort helped Wales overcome a bruising Samoan side to edge towards a rugby World Cup quarter-final berth on Sunday, while England struggled to an unconvincing win over Georgia that left coach Martin Johnson fuming. In Napier, a much-changed France side were forced to deal with wet and windy weather before overcoming Canada 46-19, making it two wins from two in Pool A. Conditions were much more favourable in Hamilton as Wales produced some entertaining rugby and fierce defence under sunny skies to claim a precious 17-10 victory over Samoa. Winger Shane Williams scored the decisive try late in the second half with fullback James Hook and flyhalf Rhys Priestland kicking six points each to secure a victory that is likely to see them claim second place in Pool D. Samoa prop Perenise crossed for a try late in the first half but they were unable to add to their tally in the second period as their burly backs were shut down by the Welsh, who made 142 tackles in the match. England faced criticism after their win in Dunedin as their old problems with discipline were evident again. Late tries added gloss to the 41-10 victory over a tiring Georgian side. England struggled to gain territory and possession against their second tier opponents leaving manager Martin Johnson frustrated. Some woeful kicking by Georgian flyhalf Kvirikashvili and six tries by England made sure there was no repeat of the upset suffered by Tri-Nations champions Australia at the hands of Ireland. The Wallabies left Auckland still stunned after their surprise defeat at Eden Park. Australias loss to Ireland means they face a probable quarter-final against South Africa and, if they survive, a last four encounter with the All Blacks. The All Blacks return to Auckland on Wednesday ahead of their clash with France. Winger Vincent Clerc completed a hat-trick of tries with the final play of the game to secure a bonus point for the French, with scrumhalf Morgan Parra adding 23 points with the boot.
