The United States lost both of its four-ball matches to England while Yani Tseng helped Taiwan to a sweep of Australia on the opening day of the UL International Crown on Thursday.

Lexi Thompson and Cristie Kerr lost 2-and-1 to Holly Clyburn and Jodi Ewart Shadoff, and Stacy Lewis and Gerina Piller were defeated by Charley Hull and Melissa Reid by the same score. Thompson, Kerr and Lewis also were on the American team that was swept on the first day of the inaugural event in 2014 and finished sixth.

Tseng and Teresa Lu went off in the first match at The Merit Club about 40 miles northwest of Chicago and cruised to a 3-and-2 victory over Karrie Webb and Su Oh. Tseng and Lu then watched as Candie Kung and Ssu-Chia Cheng posted a 2-up win against Rebecca Artis and Minjee Lee.
