This event is contested every two years between two teams of amateur women golfers -- one from the United States and one from England, Scotland, Wales and Ireland.
The schedule for Sunday is the same as it was Saturday: three morning foursomes and six afternoon singles. The U.S. side needs just two more points to retain the Curtis Cup for the fifth straight year.
Captained by Carol Semple Thompson, the all-time leader in Curtis Cup victories with 18, the American team swept the Saturday morning alternate-shot foursomes to take a 3-0 lead.
Mackenzie and Amanda Blumenherst cruised to a 5 and 4 win over Tricia Mangan and Kiran Matharu to set the pace.
Also in the foursomes, Virginia Derby Grimes and Amanda McCurdy held on for a 2-up win over Martina Gillen and Naomi Edwards, while Park and Leon birdied the last hole to defeat Claire Coughlan and Melissa Reid, 1-up.
In the afternoon singles matches, Mackenzie and Leon both rolled to 5 and 4 victories while Park claimed a 3 and 2 win. Jennie Lee was a 4 and 3 winner, but Jenny Suh and Blumenherst both dropped their matches.
Breanne Loucks handled Blumenherst, 5 and 4, and Suh lost 2 and 1 to Matharu in the lead match.
It was a good start nonetheless for the United States, which leads the all- time series 24-6-3.
In 2004, Michelle Wie helped the Americans to a 10-8 victory at Formby Golf Club in Merseyside, England.
Then just 14, Wie was the youngest player ever selected for the Curtis Cup. Her team that year also included 2005 LPGA Rookie of the Year Paula Creamer.
