Still a couple of months before Pia Sundhage has to decide on her 18-woman roster for the Olympics, but five Americans know they're headed to London for the soccer competition.
Huntington Beach's Marlene Duffy and four other referees were invited to officiate at the 2012 Summer Games. Duffy also worked the 2008 Olympics in Beijing and last summer's Women's World Cup in Germany.
The other officials are Kari Seitz and Veronica Perez for women's games and Major League Soccer veterans Mark Geiger and Sean Hurd for men's matches. Duffy and Perez have primarily worked as lineswomen internationally.
The Olympic soccer competitions begin July 26.
