AUCKLAND (AFP) - Wales beat Namibia 81-7 on Monday in their biggest ever World Cup win to cast doubt over claims that so-called 'minnow nations are making gains on rugbys giants. The Six Nations team took an easy step towards the quarter-finals with Scott Williams claiming three of their 12 tries and Stephen Jones celebrating his record 101st Welsh cap with a penalty and six conversions. With the win, Wales confirmed the elimination of Fiji, who can now only play spoilers for the Dragons quarter-finals hopes when they meet on Sunday. Wales are equal on points with Samoa, who face defending champions South Africa. Despite the yawning chasm in the scoreline, Wales laboured at times against a willing but fatigued Namibia side, who exit the tournament having conceded 266 points against 44 scored in four games. Namibia lost 87-0 to South Africa just four days earlier among a run of large scores including New Zealands 83-7 demolition of Japan, Englands 67-3 win over Romania and Irelands 62-12 stroll against Russia. The string of uncompetitive matches has made for unappetising viewing and raised questions over strong signs earlier in the tournament that 'tier-two countries were catching up with the traditional powers. Analysis by the International Rugby Board (IRB), which has invested heavily in the sports development, found that over the first two rounds, the average points difference in games between big and small countries had shrunk to 29, from 42 in 2007. Meanwhile, jubilant New Zealand media trumpeted Saturdays 37-17 win over France, which avenged two World Cup upsets and cast off a cloak of pessimism that had enveloped the All Blacks campaign. Writing in the New Zealand Herald, former All Blacks winger Jeff Wilson claimed the World Cup is ours to lose based on the emphatic victory at the teams Eden Park headquarters. New Zealand now have the formality of a final Pool A game against Canada before an expected quarter-final against Argentina, unless Scotland can upset old rivals England in Pool B on Saturday. Ireland are gearing up for a must-win game against Italy to stay top of Pool C, while Australia are expected to welcome back influential flanker David Pocock after a soaking in thermal springs speeded his comeback from a back injury. However, the Wallabies are dealing with a raft of other injury problems as they size up Russia on Saturday and a likely quarter-final against South Africa. England lock Courtney Lawes vowed not to compromise his confrontational style after serving a two-match ban for kneeing Argentinas Mario Ledesma in the head. He is now available for Saturdays much-anticipated clash with Scotland. Russian hooker Valery Tsnobiladze became the fourth player ordered before a disciplinary hearing, over an alleged head-butt in Sundays defeat by Ireland. No time or date was set for the proceedings.
