WARREN Gatland believed his Wales side had done all they could to put pressure on Ireland and England in the race to win the RBS 6 Nations title, even though in the end it proved to be not quite enough.

Wales ran riot in the Rome sunshine to beat Italy, scoring 47 unanswered second-half points before Leonardo Sarto's last-minute try trimmed the margin of victory slightly.

So Ireland started their game in Scotland needing to make 20 points up on Wales, but unfortunately for Gatland and his team, Ireland were ruthless at Murrayfield, running out 40-10 winners which moved them top of the Six Nations standings on points difference and left England needing to beat France by 26 points at Twickenham for them to claim the title.

"We spoke at half time about being accurate and we've given ourselves a shot," said Gatland straight after their match.

Wales struggled to find any momentum in a poor first-half performance and only led 14-13 at the break with one solitary try from Jamie Roberts. But they were a different side in the second half with Liam Williams' try preceding an 11-minute hat-trick from George North and further scores from Rhys Webb, skipper Sam Warburton and replacement Scott Williams. Full-back Leigh Halfpenny kicked two penalties before going off injured, but fly-half Dan Biggar proved a capable deputy, slotting a penalty and six conversions.

Italy scored an early Giovambattista Venditti try and a late Leonardo Sarto touchdown, with Kelly Haimona kicking a penalty and substitute Luciano Orquera adding a penalty and two conversions, but the Azzurri were ultimately horribly outclassed.

"We knew sitting in the box if we scored a couple of tries to get ahead of them we would break their spirit," Gatland said.

"It was a great second half performance and the biggest away win for Wales in the Six Nations is another milestone for these guys.

"I'm a little bit gutted about that last try but you can't question the performance, effort and commitment of the boys. We dug in there and 60 points is not bad.

"We've always said as a squad we get better the more time we spend together and I think we've improved as the tournament has gone on. We can look forward to the World Cup now and we know we're in such a tough group. But if we've got the players fit and available we're good enough to come out of that group and even win the World Cup."

Wales arrived in Rome knowing that an emphatic victory was their likely requirement to keep the pressure on their title rivals.

But it was a scrappy opening, with Haimona, who went off injured after only five minutes, and Orquera kicking penalties for Italy while Halfpenny converted two Wales penalties.

Centre Roberts scored the first Welsh try, winger Venditti replied for Italy before Biggar's penalty gave the Welsh a one-point half-time lead. In between, the prolific Halfpenny went off after suffering nasty blow to the head.

Both sides were unrecognisable after the break as the Welsh silenced the boisterous Italian support with a ruthless display of rugby. Liam Williams opened the floodgates when he slipped through a gap in the Italian backline before a rampaging North scored his hat-trick of tries.

Italy, meanwhile, lost their discipline as Andrea Masi and Quintin Geldenhuys were sent to the sin- bin. As the onslaught continued, scrum-half Webb forced his way through half-hearted tackling for another try before captain Warburton out-paced the Italian back line for their sixth try of the half.
