Charley Hull and surprising England grabbed the lead in the UL International Crown on Saturday, and the United States advanced with a sweep against Japan.
Hull, who missed Friday's four-ball session with a fever and trouble with her asthma, teamed with Melissa Reid for a 3-and-1 victory over sisters Ariya and Moriya Jutanugarn of Thailand. Holly Clyburn and Jodi Ewart Shadoff routed Pornanong Phatlum and Porani Chutichai 7 and 5, helping seventh-seeded England to a Pool B-best nine points.
The U.S., which began the day with just three points, qualified for Sunday's singles matches with its best day so far. Lexi Thompson and Cristie Kerr posted their second straight win with a 4-and-2 victory over Ai Suzuki and Ayaka Watanabe, and Stacy Lewis and Gerina Piller surged to a 3-and-1 victory over Haru Nomara and Mika Miyazato.
