Argentina hold off spirited Japan to reach Rugby World Cup quarter-finals

Argentina's Mateo Carreras scored a hat-trick to help the Los Pumas see off Japan 39-27 in their winner-takes-all Pool D clash on Sunday.

With both sides knowing victory would see them take second place in the pool at the other™s expense to join table-toppers England in the next round, Los Pumas sealed the spot after scoring five tries in Nantes, with Carreras the star man.

A fast start by Michael Cheika™s side saw Santiago Chocobares burst through a crowd of players to cross in the second minute, with Emiliano Boffelli successfully converting.

Jamie Joseph's Japan hit back in the 16th minute when Amata Fakatava chipped over a defender, reclaimed the ball and touched down, and Rikiya Matsuda kicked the extras, before the Brave Blossoms were reduced to 14 men by a yellow card for Pieter Labuschagne.

Carerras then registered his first try to put Argentina back in front in the 28th minute and a subsequent penalty from Boffelli - who had missed one earlier, along with his second conversion attempt - made it 15-7.

Japan again rallied, with Naoto Saito crossing and Matsuda converting to leave a point in it heading into the interval.

Carreras registered his second try, converted by Boffelli, early in the second half, before a Matsuda penalty and Lomano Lemeki drop goal closed the gap to two points at 22-20.

Argentina then wrapped things up as Boffelli scored a try and converted, and Carreras subsequently completed his treble, with Nicolas Sanchez kicking that conversion and a further penalty with five minutes left.

They will now take on Wales in Marseille on Saturday.
