Wasps flanker Thomas Young is one of three players making their Wales debuts in Friday's clash with Tonga in Auckland.

The 25-year-old, who is the son of former Wales and British & Irish Lions prop Dai Young, wins his first cap along with Scarlets wing Steff Evans and Cardiff Blues lock Seb Davies.

There are six more uncapped players hoping to make their Test bows from the replacements' bench -- front-row trio Ryan Elias, Wyn Jones (both Scarlets) and Blues' Dillon Lewis, Newport Gwent Dragons flanker Ollie Griffiths, Gloucester back Owen Williams and Scarlets scrum-half Aled Davies.

While the matchday squad is brimming with youth in general, there's an experienced look about the midfield, where captain Jamie Roberts operates alongside Scott Williams.

Wales, who will face Samoa a week later, are currently without 12 first-choice players due to the ongoing British & Irish Lions.

Wales: Anscombe, Cuthbert, S Williams, Roberts (capt), Evans, Sam Davies, G Davies; Smith, Dacey, Francis, Seb Davies, Hill, Shingler, Young, Navidi.

Replacements: Elias, Wyn Jones, Lewis, Jenkins, Griffiths, A Davies, O Williams, Allen.

Tonga: Halaifonua, Tuitavake, Piutau (capt), Tahitua, Vuna, Fosita, Takulua; Talakai, Ngauamo, Tameifuna, Fifita, Mafi, Faleafai, Latu, Mapapalangi.

Replacements: Taufalele, Puafisi, Kite, Tau, Faleafa, Fukofuka, Hala, Taimani.
