An old coach with a young team will take a shot at what would rate as one of New Zealand's more memorable sevens titles in Wellington tomorrow.Coach Gordon Tietjens and a team featuring four new caps, including 17-year-old star Rieko Ioane, will play Australia in a trans-Tasman quarterfinal, the last of some highly unexpected Cup knock out matches.USA provided the big upset on day one as they headed off series leaders South Africa in Pool A to earn a quarterfinal against Scotland, the Celts earning a top-eight finish thanks to Samoa bowing out in Pool D, while Fiji play England and Kenya play South Africa in the other quarterfinals.Tietjens had struck an unusually jumpy figure in the days leading up to the tournament after losing veteran Tim Mikkelson to a groin injury.With four uncapped players and Murphy Taramai at his first Wellington sevens, New Zealand could have brought in Fijian veterans Tomasi Cama or Lote Raikabula.Instead, Tietjens backed his gut and plumped for the new kids and they repaid his faith during wins over Canada (26-5), Papua New Guinea (38-7) and England (24-5), in the final match of the opening day.Experienced Bay of Plenty man Scott Curry produced two huge plays against England, first with a try saving tackle, then, after the match was tied 5-5 at halftime, a brilliant solo try that set the tone for the second half.Captain DJ Forbes came up with some big turnovers too, but it was the young guns who laid out the story line for New Zealand's defence of their home tournament on the IRB world series.Ioane, playing the tournament with an age dispensation, scored against Canada with his first touch in a New Zealand sevens jersey, and got the first and last tries against England.New cap Dylan Collier started the pressure-packed pool finale too, capping a day when Tietjens' hunches played out for the umpteenth time.New Zealand 38 (Ambrose Curtis 2, Jack Goodhue 2, Beaudein Waaka, Dylan Collier tries, Waaka 4 cons, Kaka con) Papua New Guinea 7 (Wesley Vali try, Eugene Tokavai con).
