The Vodafone Fijian 7s team are on track to defend the USA 7s title in Las Vegas.

The Osea Kolinisau-led side trounced Canada 31-12 in the Cup quarterfinal clash.

The Vodafone Fijians set the Sam Boyd Stadium alight when Olympic gold medal winning forward Apisai Domolailai ran in two tries as they took a 14-5 lead. But it was the magic of halfback Seremaia Tuwai who scored a classic try to put Fiji on a handy 21-5 lead at halftime.

Head coach Gareth Baber instructed his players to keep throwing the ball around and also tightened up their defence.

The Vodafone Fijians suffered a setback when Tuwai had to leave the field due to a leg injury.

His replacement Waisea Nacuqu through a solo effort scored a try from a kick and chase movement to extend their lead to 26-5.

The Canadians fought back with a converted try to narrow the deficit 26-12.

Right on fulltime a backline move saw Joeli Lutumailagi set-up Samisoni Viriviri to score in the corner leaving the final scores at 31-12.

Fiji will take on New Zealand in the second semi-final at 10.06 am tomorrow .
