On Monday, Plum prepared to make her debut for the Sparks franchise, turning heads with a unique pregame ritual that many fans had never seen before. "Kelsey Plum just moments before her preseason debut," the Sparks' X account wrote with an exhaling-from-the-nose emoji.

The Golden State Valkyries will check off another milestone Tuesday when they host the Los Angeles Sparks in their first game. Though only a preseason contest, this is a significant moment for the Valkyries, who are the first expansion team to enter the WNBA since the Atlanta Dream in 2008.

The Golden State Valkyries will hit the court for the very first time when they face the Los Angeles Sparks tonight.
