The South African women's hockey team will have to be content with a bottom-half finish to their Olympic campaign after losing 1-0 to Australia in their penultimate pool B contest in London on Saturday.
The loss ensured South Africa would not be able to compete for a semi-final place as they remained winless after four games and in danger of losing all their pool games at the London Games.
SA ended the match having created more scoring opportunities (11) compared to the Aussies' seven, but were unfortunate not to be rewarded for arguably their best performance of the Games thus far.
The South Africans conclude their campaign against the US on Monday.
