Katerina Stewart

Katerina Stewart is a professional pickleball player who ranks No. 2 in the APP Tour's pro women's singles division. A former professional tennis player who reached a career-high WTA ranking of 158 in 2015, Stewart transitioned to pickleball after an injury ended her tennis career. In just a couple of years, she's become one of the most dangerous singles players on tour.

Stewart's rapid rise in pickleball is remarkable given her relatively limited tournament experience. She reached the gold-medal match in women's singles at the 2025 USA Pickleball National Championships, earning silver behind Sofia Sewing. Her season singles record of 34-10 with two professional titles speaks to her elite level. She's also competed in mixed doubles, partnering with Ronan Camron on the APP Tour. Stewart has spoken openly about her journey of self-acceptance during her tennis career, and she brings that same authenticity and resilience to the pickleball court.
