Great Britain's women are one win away from qualifying for the 2016 Rio Olympics after beating South Africa in the World League Semi-Finals in Spain.
First quarter goals from Alex Danson and captain Kate Richardson-Walsh gave Great Britain a 2-0 win.
Danny Kerry's side are unbeaten in the competition and will face Germany in Saturday's semi-final.
The winners of that match in Valencia will guarantee qualification for the Olympics.
The losers will play either China or Argentina in the third place play-off on Sunday with the winners also advancing to the Olympics.
"We do our homework on every team," said Danson. "We play to our strengths and our tactics and that's what gets results."
Great Britain finished top of Pool A with a 100% record.
There were 10 countries competing in the World League Semi-Finals in Spain and a further 10-team tournament takes place in Antwerp in July.
Seven teams that progress from both events will take part in the World League Finals from 21-29 November in Argentina.
