Key Storylines

Wimbledon champion Elena Rybakina is back in action: San Jose will be Rybakina's first tournament since her incredible run to her maiden major title at The Championships. Rybakina made her tournament debut last year and advanced to the quarterfinals. She lost in two tiebreakers to eventual champion Collins.

Ons Jabeur ready to bounce back on hard courts: The Wimbledon finalist has had a few weeks to process being a set away from the title. Now she gets back to business. The World No.5 has made the final or better at five of her last seven tournaments, but that run came exclusively on the natural surfaces. Can she port her success onto hard courts?

Naomi Osaka returns to where it all began: Osaka made her WTA main draw debut at the Mubadala Silicon Valley Classic when the tournament was held at Stanford University in 2014. Then, the 16-year-old was ranked outside the Top 400 but worked her way through qualifying to make her main draw debut. There, she stunned Samantha Stosur in the first round for her first win on the Hologic WTA Tour. 

This will be Osaka's first appearance at the tournament since it moved to San Jose and her first tournament since Roland Garros.

Coco Gauff makes her tournament debut: The Roland Garros finalist is knocking on the door of a Top 10 debut, currently sitting behind Emma Raducanu at No.11. The 18-year-old sits at No.3 on the Porsche Race to the WTA Finals behind Iga Swiatek and Jabeur. She has made the semifinals or better at two of her last three tournaments.
