A committed Wales outfit pushed Tonga to the limit before the hot favourites prevailed 32-6 this morning.
The win leaves Tonga on track for a blockbuster quarter-final showdown against Samoa but they will need to improve their discipline and get some combinations right if they are to put up a challenge for the title.
Tonga will now face Cook Islands at 2.30am on Monday before heading into the quarter-finals, where they are set to face Samoa.
