Wales coped with an early injury to captain Ryan Jones to finish their season on a high with a 48-15 victory over USA at Toyota Park in Chicago.
Two tries from Jonathan Davies, the first for his country in his second appearance, and further scores from Mark Jones, Tom James, Gareth Cooper and a penalty try gave Wales success in its 600th international match after skipper Jones had taken a very heavy blow in the opening minute and been forced off 19 minutes later.
Wales, playing in front of a 6,262 crowd the majority of whom appeared to be Welsh supporters, had expected a physical encounter with the Americans, just as they had experienced in beating Canada 32-23 a week earlier in Toronto.
They got exactly what they expected early when Eagles prop Will Johnson landed a big hit on Ryan Jones in the opening minute.
He needed a lengthy spell of treatment before returning to the action. He was still in trouble, though, and twice needed further attention before being forced to leave the field. Sam Warburton replaced him to earn his first cap.
By then Wales were on top at 13-3, thanks to two opening penalties from Nicky Robinson, Gavin Debartolo replying for USA, and a try from Mark Jones, who finished off a move started by Deiniol Jones off a ruck. Robinson added the conversion.
It got better for Wales moments later when Robinson collected from scrum-half Peel and chipped over the top, collecting the ball and off-loading on the halfway line for outside centre Davies to run in for his first international try. Robinson again converted.
There was more collateral damage as flanker Robin Sowden-Taylor joined fellow back rower Ryan Jones on the bench after tweaking a hamstring.
Reserve hooker Richard Hibbard was sent on at blindside with Warburton already at openside, Dafydd Jones having taken over at number eight when Jones went off to form a very unfamiliar back row, with prop Duncan Jones taking over the captaincy.
American zeal strayed over into indiscipline when back row Louis Stanfill was sin-binned by referee Matt Goddard for bringing down a maul and a minute later the Australian official awarded a penalty try to Wales when Dafydd Jones was denied a try as the Wales pack pushed over.
Eagles back rowers Peter Dahl and Nic Johnson both went deliberately offside to prevent the touchdown. Robinson converted from in front of the posts and Wales went in at the break 27-3 up and well in control.
The USA had lost 27-10 to Ireland in California last Sunday and there was still life in the Eagles in Chicago as they nullified the Welsh threat and started to gain territory of their own.
Their reward came in the 53rd minute when centre Alipate Tuilvuka crashed through tackles from substitute lock Luke Charteris and Peel to give the USA their first try of the game. Debartolo added the conversion to cut Wales' lead to 17 points.
Jonathan Spratt came off the Wales bench for full-back Daniel Evans and nearly had a hand in a fourth try for the tourists only for his pass outside to Tom James, who subsequently went over the line, to be ruled forward in the 59th minute.
James did get his try four minutes later, pouncing on a ball that ricocheted off his boot near the USA 22 to pick up on the try line and touch down. Robinson converted with his last kick of the game before making way for Dan Biggar.
Cooper replaced James and he got on the scoresheet when Biggar kicked ahead, the 30-year-old scrum-half beating the 19-year-old fly-half to the ball to touch down. Biggar was left to kick the conversion.
Davies added his second try of the afternoon with two minutes to go, Biggar converting again for another perfect outing from the Wales kickers.
The Americans, building for a World Cup qualifying tie with Canada next month, added their second try in the final minute when sub JJ Gagliano got over the line, but Debartolo missed the conversion.
Wales centre Jonathan Davies admits he is yet to fully come to terms with his devastation after club side Clermont Auvergne suffered a heartbreaking loss in their European final with Toulon on Saturday.
