USA shift the ball to the left wing before playing a grubber kick for Telesi Uhatafe to chase.
The ball instead runs out for a Welsh line-out, which the hosts win. However in the first phase of play afterwards Sisilia Tuipulotu spills the ball forward once again, and now the USA have a scrum inside the Welsh 22.
Bit of flair being shown from the visitors, as scrum-half Abigail Paton pulls off a no-look, one-handed offload that the Harlem Globetrotters would have been proud of.
Wales retain possession at the scrum and move the ball to the left wing, but are penalised at the first breakdown for holding onto the ball.
The American replacements in the stand are celebrating every penalty like they've scored a try. The whole travelling contingent seem really up for this game today.

Wales have struggled with their discipline over the last few years.
It was outstanding last week but there have been some early penalties here and Sean Lynn has been training them not to give easy yards like they have been so far.
