Background
The 2020 season was the Washington Spirit's seventh season. The season was slated to begin on April 18, 2020 but was postponed due to the COVID-19 pandemic. Ultimately, the NWSL season was cancelled due to the pandemic. The club participated in the NWSL Challenge Cup and the NWSL Fall series which were held in lieu of the regular season. The Challenge Cup was held behind closed doors at the neutral venue of Zions Bank Stadium in Herriman, Utah. The Spirit reached the Quarterfinals of the Challenge Cup, and finished in third place in the Fall Series.
