Seattle Tennis Club has hosted the WSO since 1890. This is the largest & oldest tournament in the Pacific Northwest, with $24,000 in prize money!

There is no cost to attend and concessions will be available. The Blue Angels are also an exciting part of the tournament during SeaFair weekend, flying low over the club and tipping their wings to spectators! Support our Title Sponsors:
