15. Lee Byrne: 4/10
Wales’s lack of depth at full back has given Byrne a virtual free ride in the fifteen shirt over the last few seasons. On merit he has rarely shown the form to justify. This match was a case in point, where he had a nightmare, especially when putting boot to ball.
14. Leigh Halfpenny: 6/10
An encouraging return from a long stay on the sidelines, demonstrating the genuine pace he possesses with one or two runs, but suffered from Wales’s lack of possession.
13. Jonathan Davies: 6/10
Davies looked a threat in the outside centre channel, with some incisive breaks at key times, but like the rest of the Welsh back line suffered due to a lack of ball.
12. Jamie Roberts: 5/10
A quiet day at the office, Roberts usual impact at the gain line was nullified by the Argentinian defence, and offered little creative spark. Defensively vital though.
11. George North: 7/10
A performance to really whet the appetite of Welsh supporters. Argentina struggled to cope with his physicality and pace the few times he was in possession. Finished his try well and showed terrific composure in the build up to the second Welsh try.
10. James Hook: 7/10
Not as effective as the week before against England, but still produced an above average display. Good game management and excellent defence was only let down by a lack of creativity.
9. Tavis Knoyle: 7/10
The 21-year-old rose to the occasion of his first test start with a confident performance, one he capped off with a try. Question marks still linger over his service, but a very encouraging afternoon for the Scarlets player.
1. Paul James: 6/10
Looked a lot more comfortable in the scrum, undoubtedly benefiting from the change in front-row personnel. Excellent defensive work-rate, but anonymous elsewhere.
2. Richard Hibbard: 6/10
Unsurprising the Ospreys’ man appeared a little rusty on his return from injury, but showed signs of being the man to fill the hooking void left by Matthew Rees’s injury, making the ankle injury that has ended his World Cup hopes, even harder to stomach.
3. Adam Jones: 7/10
A world class scrummager, Jones demonstrated what Wales have clearly been missing without him. Quiet elsewhere, but a highly influential figure in the set piece.
4. Bradley Davies: 5/10
Struggled to impose himself against the physicality of the Pumas’ and was far from the ball carrying presence of previous seasons.
5. Alun Wyn Jones: 7/10
On the third-time of asking this summer, Jones produced a performance somewhere near to befitting his reputation. An athletic display typified by his part in the first Welsh try.
6. Dan Lydiate: 6/10
After the high of last week, this was more of a low for the blindside flanker. In particular, he was considerably less influential at the breakdown.
7. Martyn Williams: 5/10
As much as everyone in Wales wants the veteran to recapture his former glories, performances such as this one are indicative of a player who is very much on the wane. Some impressive touches and a couple of turnovers to his name, but Williams on the whole had little influence at the breakdown.
8. Andy Powell: 7/10
Wales’s most impressive ball carrier off the few scraps he had and was highly influential in defence. Powell will have significantly boosted his World Cup hopes.
16. Huw Bennett: 5/10
Played the final quarter, but in hindsight it would have been better for Warren Gatland to look at another hooker that was not certain to go to the World Cup.
17. Ryan Bevington: 5/10
Replaced Paul James with fifteen minutes to go. Wales are yet to see if the youngster is anything other than bench-filler material.
18. Jonathan Thomas: 5/10
A last gasp chance for Thomas to re-ignite his World Cup hopes after replacing Lydiate for the final twenty-minutes. Had very little impact on proceedings, perhaps a fair summation of his last year or so in test rugby.
19. Justin Tipuric: 6/10
Touted as the next big thing in Welsh rugby, Tipuric will be disappointed not to have started, only playing the final ten minutes, with the game as good as over as a contest.
20. Lloyd Williams: 5/10
A few good touches from another young replacement, but looked a little tentative, unsurprising for a player with only one full season of regional rugby behind him.
21. Scott Williams: 5/10
On as an injury replacement for Roberts, Williams made little impact, other than a few solid carries in midfield.
22. Aled Brew: 6/10
Brew looked hungry for ball through out the twenty or so minutes he was on the pitch, but ended up with few chances to enhance his World Cup prospects as the lack of Welsh creativity told.
