They only need two and a half points from the eight singles matches tomorrow
Great Britain and Ireland lead the USA 8-4 at the Curtis Cup at Dun Laoghaire Golf Club.
The United States have won eight of the last nine contests between the top female amateurs from both sides of the Atlantic.
But Great Britain and Ireland won five of the six points from today's Day 2 action.
That means they only need two and a half points from the eight singles matches tomorrow to secure victory.
