Wales coach Robin McBryde has thrown down the gauntlet to incoming fly-half Nicky Robinson to match Dan Biggar's performance against Canada in Saturday's Test against the United States.
Robinson comes into the Wales starting XV alongside recalled scrum-half Dwayne Peel, with Biggar and Gareth Cooper dropping to the bench following the 32-23 victory over Canada in Toronto last weekend.
There are three other changes from the team that started against the Canadians, with Scarlets wing Mark Jones, recovered from a knee injury and Ospreys lock Ian Gough and Blues hooker Gareth Williams drafted in to face the Eagles in what will be Wales' 600th international.
For Robinson, 27, it will be his first cap for three years, the last of his 12 appearances coming on the 2006 tour of Argentina.
Now McBryde wants the Blues fly-half to justify his selection by matching Biggar's effort against the Canucks last week, when the 19-year-old Ospreys player kicked eight for eight and earned the man-of-the-match award in his first international start.
"It was a tough call on someone like Dan Biggar, who was man of the match, deservedly so, against Canada and it's not a reflection on his performance," McBryde said. "He did all that he could and he's really set the standard for Nicky.
"Nicky deserves a start, we feel, so I'm sure he'll be looking to make the most of it, as will Gareth Williams, who's had to wait quite a long time for his start, and Mark Jones was carrying an injury last week so he's keen to get in the fray as well.
"We're adding a bit more experience but I think along with Dwayne Peel at number nine it adds a certain edge to the team as well. They want to go out there and prove a point."
Robinson, McBryde said, was well worth his place in the starting XV: "He's been playing well with the Blues, he's had some high-intensity matches under pressure and shown a level of composure in being able to keep Cardiff in games or pull away from other teams.
"His kicking game, his all-around passing ability, he's a running threat and I think he's got a good balance to his game at the moment, hence his inclusion on the trip and he's got an opportunity on Saturday."
The RBS 6 Nations Championship 2015 was not poised to go down as one of the more "vintage" Championships, though there was great anticipation as the action headed into its final day. What transpired was something that nobody could foresee: "The Greatest Day in Rugby's Greatest Championship."
