Riley has been a free agent since the demise of league champions FC Gold Pride in November.
As well as winning a championship in 2010, Riley’s debut professional season also involved individual recognition in the form of the WPS Rookie of the Year award.
Formerly known as the Buffalo Flash and coached by former All White Aaron Lines, the Flash were invited to join the WPS after winning the second tier W-League competition.
Lines is excited about Riley putting pen to paper.
“It’s an honour to bring a player from my home country to the Flash in our inaugural season in the WPS,” he says.
“Ali’s athleticism, international experience and pace will be a great addition to our team and I’m looking forward to working with her.”
Riley is one of four Football Ferns playing professionally around the world. Rebecca Smith stars for VfL Wolfsburg in Germany, Kirsty Yallop for Kristianstad in Sweden and captain Hayley Moorwood is at English club Chelsea.
The Football Ferns will play Japan, England and Mexico at the FIFA Women’s World Cup in Germany next June and July.
