The South African men's hockey team started their campaign at the Tokyo Olympics with a loss to Great Britain.
In a brave display in which they were forced on the back foot for most of the match, South Africa eventually went down 3-1 after holding their more fancied opponents to a 1-1 scoreline at half-time.
Sam Ward opened the scoring for Great Britain before Matthew Guise-Brown drew South Africa level.
As the game went on, however, Great Britain wore down the South African defence and despite the heroics of Rassie Pieterse in goal, they scored further goals through Liam Ansell and Jack Waller.
South Africa are now up against the Netherlands who lost 3-1 to Belgium.
That Group B match takes place on Sunday, 26 June 14:15.
