LONDON — Scotland played with aggression, discipline and attacking ambition to beat Italy 34-10 in the Six Nations Saturday. Tries from Tim Visser, Matt Scott, Stuart Hogg and Sean Lamont as well as 14 points from the boot of Greig Laidlaw helped Scotland overwhelm an Italy team who came into the match full of confidence after beating France last weekend. It was Scotland's first win in this year's championship after it was soundly beaten 38-18 by England on the opening weekend. In a match often billed as the wooden spoon decider, Scotland was superior in all areas and capitalised on a string of Italian errors to win its first match at Murrayfield after five successive defeats. Samoa begins in style Defending champion Samoa came from 12-0 behind to beat Spain 19-12 Friday on the opening day of the US stop in the IRB Sevens World Series. Captain Afa Aiono scored the winning try under the posts, delighting a vocal contingent of Samoa fans at Sam Boyd Stadium. Samoa closed the night with a 12-7 Pool D victory over the United States, who had lost their opening match to Australia 26-7. Spain rebounded with a 24-14 win over Australia. In Pool A, Fiji won both of their opening-day matches, hanging on for a 14-12 victory over Scotland when Russell Weir missed a last-minute penalty drop goal. England, champion at Wellington last week, lost both of its two matches — 21-5 to Portugal and 26-17 to Fiji, who had two tries from Samisoni Viriviri. In pool B, South Africa also ended the day with a perfect 2-0 record. They routed Uruguay 45-0 then followed up with a 17-5 victory over Canada. New Zealand also take momentum into the second day after conceding just five points in two day-one victories in Pool C. Belgium Tuatagaloa scored two of New Zealand's three tries in a 21-0 victory over France. Ben Lam had a hat trick in a 40-5 victory over reigning Rugby World Cup Sevens champions Wales. — Agencies
