The 63kg saw a much closer affair as three-time Asian junior champion Ayana Gempei eventually managed to secure victory against Braxton Rei Stone of Canada by a 10-8 scoreline.

However, the final match of the day in the 75kg category, again between a Japanese and Canadian contest, was yet another thrashing, as Yasuha Matsuyuki defeated Gracelynn Doogan 12-2.

Tomorrow is the penultimate day of the event and once again features women’s wrestling events with medals in the 48kg, 53kg, 60kg and 69kg set to be contested.
