South Africa beat Italy for the first time with a 29-24 victory in York to seal a maiden Women's Rugby World Cup quarter-final, and were joined in the last eight by France, Ireland and New Zealand on Sunday.
Seven of the eight quarterfinalists have now been confirmed with one round of pool matches to be played next weekend, after England, Canada and Scotland advanced on Saturday.
Only the second team from Pool A has yet to be decided, with Australia and the United States still in the running.
