Kiara Romero and Asterisk Talley birdied five of their last seven holes to beat Lily Hirst and Nelly Ong 4&3 and while Sophia Fullbrook and Patience Rhodes birdied four of the last nine holes to beat Anna Davis and Avery Weed 3&2, Beth Coulter and Isla McDonald lost their tight morning fourballs 1 up to Jasmine Koo and the outstanding Farah O’Keefe.
It meant GB&I lost the session 2-1, making it 6-3 to the US.
But the visitors, who are seeking only their second away and the first for 40 years, took the afternoon foursomes session 2-1 to make it 7-5.
Charlotte Naughton and Davina Xanh beat Americans Anna Davis and Asterisk Talley 3&2 and Sophia Fullbrook and Patience Rhodes held off Kelly Xu and Kary Hollenbaugh to win 2 up.
But Coulter and McDonald O’Brien fell 4&3 to Avery Weed and O’Keefe, who can become just the fourth player in Curtis Cup history to go 5-0.
Coulter will play in the anchor singles for GB&I as Rhodes, Fullbrook, Ong and McDonald-O’Brien play in the first four matches.
“We’ve got to win early,” skipper Matthew said.
