Cup quarterfinals

New Zealand v United States

After the United States initially put up some stern resistance, New Zealand absolutely demolished anything in front of them - physicality setting them apart.

Yellow cards to New Zealand captain Tim Mikkelson and American counterpart Madison Hughes was followed by tries by Ben Lam and Augustine Pulu - which gave the Kiwis a 12-0 lead at half-time.

Rieko Ioane and Mikkelson added tries after the break as New Zealand's greater physicality saw them race to a comfortable victory.

Fiji 28-12 Kenya

Early tries by Isake Katonibau and Savenaca Rawaca put Fiji in command against an error-prone Kenyan team. Rawaca scored a second try - to take his tally to six so far in Sydney - to give Fiji a 21-0 lead at the break.

Kenya hit back with an early second-half try through Oscar Ayodi, but Viliame Mata restored Fiji's dominance when he went over with four minutes remaining.

Ayodi got a second try with just under two minutes remaining, but Fiji held on for a comfortable win.

England 12-17 Australia (in sudden-death extra time - the teams were level 12-all after regulation time)

James Rodwell opened the scoring in the third minute, after a nervous start by both teams. Australia had their chances, but a combination of stern English defence and the Aussies' own high error count kept them scoreless till after the hooter for half-time had already sounded. Lewis Holland sneaked around the blindside of a ruck to get the hosts on the board - making it 7-all at the break.

The feisty nature of the contest continued after the break, with England regaining the lead through Tom Mitchell  - following some great interplay between the English players - with three minutes remaining on the clock.

Henry Hutchinson then did well to break a cover tackle and get Australia's second try, making it 12-all with just seconds remaining on the clock and the game went into sudden-death extra time.

After an early England rush, a turnover and a hack-forward, Hutchinson found a way over around the blind side of a ruck to score the winner.

South Africa 26-0 Argentina

Cheslin Kolbe opened the scoring early, as South Africa pounced on an Argentina mistake and worked the ball through the phases. Los Pumas struggled to find a way through the BlitzBoks' defence and resorted to kicking, before Kolbe's sublime stepping created a second try for the playmaker - giving SA a 12-0 lead at the half-time break.

Some powerplay by Francois Hougaard, which won a breakdown turnover, allowed the stepping of Rosko Specman to set up a try for Seabelo Senatla early in the second half. Argentina's high error count further contributed to their downfall, with Albertus Smith - having recovered from a shoulder injury he suffered on day one - pouncing on another turnover for the BlitzBoks' fourth try.

Bowl quarterfinals

Portugal 31-17 Japan

After a tense first half, which ended level at 12-all, Portugal raced into a 31-12 lead with tries through Miguel Lucas and Joao Belo (two), before a late consolation score by Japan.

Samoa 28-24 Russia

Samoa had raced into a 21-0 lead, which became 21-7 at half-time, and then held a 28-7 lead just after half-time, before a late rally gave Russia some respectability.

Wales 21-32 Canada

Another game where an early lead was enough to hold off a late rally - Canada racing to a 17-0 advantage, which became 22-7 at half-time. That became 27-7, before Wales closed the gap to 21-27, but a late try by Harry Jones sealed the win for the Canucks.

Scotland 22-19 France

France, despite taking an early lead, were trailing 7-17 at half-time. When James Farndale scored soon after the restart, the 22-7 lead seemed insurmountable. France rallied with two late tries, but ultimately ran out of time.
