Wales bagged a second consecutive win over a Pacific team, beating Manu Samoa 19-17 after trailing for most of the match.
Wing Steffan Evans scored in the 72nd minute to win it for Wales.
Earlier Alapati Leiua and Manu Leiataua had crossed the line for Samoa.
Robin McBryde told BBC Wales his team showed immense character.
"After going 10-0 down early on in the first half, it's like 20-0 in these conditions, you know, and we stayed in there and we soaked it up," McBryde said.
