Starfire features fields for indoor and outdoor soccer, and occasionally rugby union games, as well as a 4,500-seat soccer stadium previously used by the USL Seattle Sounders and the Seattle Reign FC of the NWSL and now used by the MLS Seattle Sounders FC for US Open Cup matches, the Seattle Sounders FC 2 of the United Soccer League, the Seattle Sounders Women of the W-League, and is the home pitch for the Seattle Seawolves, Major League Rugby team. It was also the home of Hibernian and Caledonian F.C. and FK Pacific of the Pacific Coast Soccer League. Additionally the complex hosts the annual All Nations Cup. The stadium field in 2004 became only the eighth American artificial-surface pitch to earn "recommended" status by FIFA and was thereby sanctioned for international play.
