Defending champions the United States made a strong start against Europe in the Solheim Cup, taking a 5.5-2.5 lead in Iowa.
After consecutive Solheim Cup defeats to Europe, USA won the biennial women's tournament in Germany two years ago.
The Americans moved a step closer to defending their crown thanks to a clean sweep of Friday's four-balls at Des Moines Golf and Country Club.
Europe - led by captain Annika Sorenstam - started strong by edging the morning foursomes 2.5-1.5 thanks to Anna Nordqvist/Georgia Hall (3 and 1 against Paula Creamer/Austin Ernst) and Karine Icher/Catriona Matthew (1up over Stacy Lewis/Gerina Piller).
Danielle Kang and Lizette Lalas had gone 1up against Carlota Ciganda and Caroline Masson, while Melissa Reid/Charley Hull versus Cristie Kerr/Lexi Thompson was halved.
That is as good as it got for the Europeans as Team USA dominated the four-balls in front of their home fans.
