​Wales’ only victory in five meetings against USA came in a WXV warm-up in Colwyn Bay three years ago [Huw Evans Picture Agency/Getty Images]Resurgent, inspired, unrecognisable, brave – pick one. Each describes Wales’ performance against South Africa in their WXV opener. Sean Lynn’s side scored eight tries against one of the rising forces in women’s rugby in one of the best displays of their professional era.But they know they cannot afford to bask in glory. Wales must now prove they are more than a one-hit wonder when they return to Cardiff Arms Park on Saturday.The next – and even bigger – challenge is USA, who, like the Springboks, have rocketed up the world rankings and are now a top six team. The Eagles looked down and out in Dublin, but scored 28 unanswered points to secure a remarkable comeback victory over Ireland.So we have two teams with confidence and momentum and two teams who are backing themselves to back it up. It should make for an interesting contest.Team newsOne of the few disappointments against South Africa is that Wales did not see more of the promising Keira Bevan and Seren Lockwood half-back partnership.Lockwood failed a first-half head injury assessment which paved the way for Lleucu George to reclaim the 10 shirt, with Bevan moving back to scrum-half.And that is what Lynn has gone with this week. He has also recalled Carys Cox, who replaces Seren Singleton on the wing after the former’s recovery from knee surgery in the summer.Georgia Evans will win her 50th cap, while there are three new faces on the bench in Molly Reardon, Sian Jones and Nikita Prothero.Wales recall George and Cox to backline for USAWales suffer scrum-half Lockwood blow for USA TestUSA have also had a bit of a reshuffle after their triumph in Dublin, with theirs being a six-day turnaround compared to Wales’ eight. Head coach Jack Hanratty has given Nina Mason a start at fly-half after impressing on her debut.Mason’s Life University team-mate Bella Vogel shifts to inside centre to accommodate Emily Henrich at 13, while Katana Howard joins the replacements. Lleucu George returns to Wales’ starting line-up having been a replacement in the last two games [Huw Evans Picture Agency]Test form guide Wales ended a run of nine consecutive Test defeats against South Africa and will be looking to make it back-to-back Test wins for the first time in the Sean Lynn era.Wales 50-19 South AfricaWales 24-43 ItalyIreland 33-12 WalesEngland 62-24 WalesWales 7-38 FranceUSA are on a decent run, having beaten Ireland and South Africa in their last two outings.
