Wales have reshuffled the backline ahead of Saturday’s Nations Championship clash with Argentina.

Wing Louis Rees‑Zammit sits on the bench while Sam Costelow starts at 10, a move that follows a string of changes after fly‑half Robert Edwards F‑M. Costelow’s 16‑point display against Italy kept him in the mix and now backs the squad for a top‑flight test.

Edwards, who missed the February test against Scotland, returned to finish the series with a 16‑point haul against the Azzurri, ending a three‑year losing streak in the Six Nations. The decision to drop him at the last minute after a tough outing against Fiji signals a shift toward a more dynamic, high‑tempo attack.

The selection also highlights the Scarlets’ dominance in the backline, with five of the seven backs hailing from the club. Joe Hawkins will cover fly‑half duties after Edwards exits, while centre pair Teddy Williams and Eddie James add depth. The bench includes veteran Elias and young James who could earn his first cap.

If Wales can impose their preferred tempo on Argentina, the match will test the cohesion of the new line‑up and set the tone for the remainder of the championship.
