Crystal Dunn scored the decisive goal in the third minute of second-half stoppage time and the host Portland Thorns advanced to the NWSL championship game with a 2-1 victory over the San Diego Wave on Sunday.

The second-seeded Thorns will face the Kansas City Current in Saturday’s title game in Washington D.C. Kansas City defeated top-seeded OL Reign later Sunday.

Dunn’s winner was a right-footed shot from the center of the box that found the top left corner of the net.

“It was a good ball in,” Dunn told CBS Sports Network of a loose ball that came her way. “… I thought, ‘Strike this as hard as you can,’ and just hoped nobody blocks it.”

Third-seeded San Diego took a 1-0 lead in the eighth minute on Taylor Kornieck’s header off a cross from star Alex Morgan. Portland tied the score in the 20th minute on Raquel Rodriguez’s right-footed shot.

The Thorns have won two NWSL titles (2013, 2017).
