Japan coach Eddie Jones was left frustrated after their final match in the Asia Rugby Championship 2015 against Hong Kong was abandoned after 13 minutes due to torrential rain causing the pitch to flood.

The Brave Blossoms had already been crowned champions before the finale at the Aberdeen Stadium on Saturday and were leading 3-0 – thanks to Ayumu Goromaru’s penalty – when referee Chris Linwood called the teams off the pitch.

A 20-minute rain delay was extended by another 20 minutes but conditions did not improve and resulted in the match being abandoned and organisers to declare it a 0-0 draw, ending Japan’s perfect record of bonus point wins in the competition’s history.

The draw gave Hong Kong three points to secure second place in the standings behind Japan and condemn Korea to bottom place in the Top 3

“We had a number of guys out there playing for World Cup spots and it is quite disappointing in terms of individuals and what the team wanted to achieve,” admitted Jones.

With the match declared a draw, Japan will fall two places to 13th in the World Rugby Rankings – slipping below Fiji and Tonga – while Hong Kong climb above Korea and Belgium into 25th.

Another side preparing for RWC 2015 are Argentina and a youthful Pumas side proved too strong for Paraguay, running out 71-7 winners at the Estadio Heroes De Curupayty in Luque to retain the CONSUR Cup. The win had no impact on the rankings with the two sides separated by 27 places.

Two other matches resulted in a positional change in the latest World Rugby Rankings with Ukraine climbing one place to 30th after beating the Netherlands 18-10 in their European Nations Cup Division 1B encounter in Odessa.
