Isoa Damudamu: The England ace breaks away against Argentina
England came through their opening game of the Hong Kong Sevens unscathed, but both Wales and Scotland suffered defeats.
England trailed Argentina twice in the latest leg of the HSBC Sevens World Series before Ben Ryan's men were able to secure a 19-10 in their only match on Friday.
Tries from Dan Norton, Rob Vickerman and Mat Turner sealed the win - with games against Samoa and Kenya to follow on Saturday. USA Sevens champions Samoa opened up their challenge in Pool A with a 19-7 win over Kenya.
Wales were left to rue missed chances as they lost 10-0 to South Africa - with Boom Prinsloo and Cecil Afrika scoring the tries.
Wales will face New Zealand and the USA on Saturday. Despite missing leading try-scorer Frank Halai, vice-captain Lote Raikabula, Solomon King and Toby Arnold, New Zealand were still too strong for the USA as they won 29-5.
Scotland's hopes of causing an upset against Fiji quickly vanished as they were thumped 39-5, with Australia toppling France 31-10 in the other Pool C game.
