Wales beat Italy 29-17 on Saturday to claim their first win in this year's Six Nations and strike a blow in the battle to avoid the wooden spoon.Rio Dyer, Liam Williams and Taulupe Faletau all touched down in Rome with a penalty try adding to their score, claiming a bonus point victory and condemning Italy to their 25th straight home defeat in the competition.Owen Williams also kicked seven points in a win which belied pre-match talk of the hosts being favourites against a Wales team which has had a troubled tournament.Warren Gatland's side leapfrog the Italians into fifth place on five points and will avoid finishing in last place for the first time in 20 years as long as the Azzurri don't beat Scotland at Murrayfield next weekend. AS IT HAPPENED | Six Nations: Wales 29-17 Italy Wales, who round off their campaign against France in Paris, had only scored three tries in their first three defeats but capitalised on an error-strewn performance from the Italians who without star full-back Ange Capuozzo regressed into bad habits of old.Kieran Crowley's Italy will have to go back to the drawing board after accruing a huge amount of good will with previous displays, in particular against France and Ireland.They dotted down through twice through Sebastian Negri and Juan Ignacio Brex, with Tommaso Allan kicking seven points, but were always chasing the game at Rome's Stadio Olimpico.
