In 2014, following a season-ending injury to Adrianna Franch, the Western New York Flash signed Lydia Williams to be their starting goalkeeper. Williams started 14 games in goal for the Western New York Flash. The Katanning, West Australia native recorded two shutouts in 2014 prior to tearing her ACL while participating in the 2014 AFC Women’s Asian Cup with the Australian Women’s National Team, an injury that ended her NWSL season. In September 2014, Williams was waived by Flash and was selected by Washington Spirit for the 2015 season. She was not on the roster for the Washington Spirit at the start of the season. She is currently unaffiliated with a professional team and is a current member of the Australian women's national soccer team.
