Europe overcame a spirited rally by the United States in the fourballs to lead 4½-3½ after the opening day of the Solheim Cup at Killeen Castle in Ireland.
Michelle Wie and Cristie Kerr defeated Maria Hjorth and Anna Nordqvist in the morning round.
With the sides even at 2-2 following the morning foursomes, rookie Caroline Hedwall and fellow Swede Sophie Gustafson put Europe 3-2 ahead with a 5 and 4 win over Vicky Hurst and Brittany Lincicome.
Europe was up in the other three matches at that stage but Morgan Pressel and Paula Creamer came back from one down with two to play to beat Europe's Laura Davies and Melissa Reid by one hole. Pressel made a 25-foot birdie putt on the 18th for the win.
Wie and Kerr lost to Suzzan Pettersen and Nordqvist in the afternoon 2-up.
Wie was not placed in the morning pairings for Saturday. She could be assigned to the afternoon round.
