"We were given a thorough test by a very good Italian side" said winning coach Simon King " but we kept our patience and eventually finished in style by running in some fine tries."
"Three tries in ten minutes reflected our good levels of fitness and ability to strike from deep despite being under a bit of pressure."
There was little to choose between the two sides for most of the game.
The bigger and bulkier Italians had the edge in the contact area but the Wales backrow trio of Ed Siggery, David Barry and Tom Young (later Ben Thomas) was quicker to the ball in the loose.
At the line-out Wales were well served by the Ospreys pair of locks Lloyd Peers and Macaulay Cook both of whom also carried the ball well in the loose.
Wales led 8-3 at the break through a penalty by full-back Tom Prydie and a try from flanker Young, son of watching Blues coach Dai Young.
The try was made by a surging run from the very impressive Prydie and finished off by a 20 metre sprint from the ever-present Young.
Italy's only score had been a penalty from fly-half Alberto Bonifazi although Bonifazi and lock Gianmarco Duca missed a further three penalties between them.
The visitors harried Wales into uncharacteristic mistakes and when the fly-half's penalty made it 8-6, there were a lot of anxious faces in the 1,000 crowd.
Wales at last came out of their slumbers with a real vengeance in the last ten minutes, showing a pace and invention that the Italians could not match.
It all started with a try four minutes from normal time by the outstanding Welsh forward, prop Rhodri Jones after a careful build-up by backs and forwards.
With the pack at last getting well behind the Italian gain-line, replacement scrum-half Adam Jones and centre Jack Gadd finished off fine combined moves with tries.
And with Prydie adding three far from easy conversions, the poor Italians looked at the scoreboard in some disbelief.
