Prior to the start of the season, it was announced that the Thorns would play their first six games on the road due to ongoing renovation at Providence Park. The Thorns would start the season strong, losing only one of their first six games before going on a run that would see them lose once in a nine-game stretch that spanned June and July. This run included the return of several key players who had missed time for the FIFA Women's World Cup, including Lindsey Horan, the reigning NWSL MVP, and team captain Christine Sinclair. The Thorns fine form was encapsulated by a 5–0 rout of the Houston Dash on July 24. Beginning the month of September at the top of the table and contenders for the NWSL Shield, the team entered what would be the worst run of form since Mark Parsons was named head coach. Portland would lose three of their final five games, including an embarrassing 6–0 loss to the North Carolina Courage which would end up as the most lopsided loss in team history. After finishing the season with a scoreless draw against the Washington Spirit, the Thorns finished third in the league, meaning they would not host a playoff game for the first time since 2015. The Thorns would be knocked out of the playoffs after a 1–0 defeat to the Chicago Red Stars.
