On May 2, 2012 the Portland Timbers partnered with the Portland Rain and the Oregon Youth Soccer Association's (OYSA) Girls Olympic Development (ODP) program. This precursor to the NWSL announcement the following November was to facilitate an integrated development structure for Oregon's girls youth soccer to elite women's competition.[6][7][8] After the start of the NWSL, in the 2013 WPSL the Portland Rain spot was replaced by a Timbers Alliance club Westside Timbers and Tualatin Hills United Soccer Club (THUSC) Diamonds. These two teams join the Oregon Rush (2011), now Bend FC Timbers, and Eugene Metro Futbol Club (EMFC in 2012) so Oregon has a total of four WPSL teams at this level of the American soccer pyramid.[9][10][11]
