The dogged Americans then hit back through Mile Pulu and with Nese Malifa adding the conversion USA had hit the front with a slender 7-5 lead.

Jevon Groves raced over to regain the lead for Wales before it was USA's turn to lose a man when Malifa received a yellow card.
Pulu scored his second try of the match before Ifan Evans restored the lead with a five pointer as Wales edged ahead 15-12.
The Samoans, already buzzing after beating New Zealand in their opening game, dominated from the outset to claim a comfortable 26-0 victory.
Captain Lolo Lui and Reupena Levasa were the heros for Samoa. Lui bagged a try and knocked over three conversions while Levasa raced over for a brace of tries. Samoa led 12-0 at the break and rubber stamped their authority in the second half with tries by Afa Aiono and Levasa.
Wales then had to overcome New Zealand to reach the main draw on day two but despite being in the hunt at halftime, the Kiwis stormed away in the second half to win 17-10.
Zac Lawrence and Ashley Beck traded tries in a keenly contested first half but the Kiwis clinical finishing proved crucial in the second spell.
Sherwin Stowers scored twice to put the pool favourites ahead before Wales finished strongly through Alex Cuthbert.
