LAST year Ollie Griffiths earned glowing praise from legendary Wales flanker Martyn Williams and this season it's his Newport Gwent Dragons teammate Harri Keddie who has caught the eye of World Cup winner Lewis Moody in the Under-20s Six Nations.

The 19-year-old from Llanvaches was named man of the match as the Welsh youngsters moved to within 80 minutes of a Grand Slam thanks to a crushing 42-16 victory against England.

They ran in six tries in a stunning performance at Ashton Gate in Bristol with number eight Keddie on the scoresheet along with flanker Shaun Evans, centre Harri Millard, fly-half Dan Jones and wing Keelan Giles (2).

The Dragons prospect has started all four of Wales' wins but, unlike some of his colleagues, is yet to make his professional debut.

Before the win against Scotland he told the Argus about the need to be patient but it's only a matter of time before Keddie, who has been learning his trade with Ebbw Vale in the Principality Premiership, makes the next step.

Former flanker Moody, a key member of the England side that lifted the World Cup in 2003, was impressed by the strong-running, hard-hitting blindside/number eight.

"(Taulupe) Faletau will be slightly concerned! There's a young man there who is big and powerful, an all-round class act and I thoroughly enjoyed watching him play," he said on Sky Sports.

Keddie was the standout player but was quick to state that the spoils were secured in such stunning fashion by the Wales squad being a tight unit.

"The boys were excellent from the first whistle to the last. From 1 to 23 it was an outstanding effort," said the forward, who was a key member of last season's team in the Six Nations and World Rugby U20 Championship.

"A lot of the boys have come back from last year, so have that extra year of experience and the unity and bond is excellent.

"Everyone gets on really well in the squad and it makes for performances like that – we know we've got each others' backs both on and off the field."

Wales have already secured their first Triple Crown since the tournament changed from Under-21s to Under-20s in 2008 and it will take a massive upset by Italy to deny them a first Grand Slam and title.

Head coach Jason Strange said before the game in Bristol that it would be their biggest test but his young charges came flying out of the blocks to lead 28-3 after half an hour.

"The players dealt with the pressure of a big game and some of the rugby they played, particularly in first half, was outstanding and huge credit to them," said the former fly-half.

"We think we've got a special group of players, on and off the field, and they've got one fantastic characteristic and that's that they work extremely hard.

"You've always got a chance when you've talent and work hard, a lot of them have got special futures."
