Katherine Sebov

Canada

Sebov reached a career-high No. 136 in April 2023, and the ITF lists hard and grass as her preferred surfaces. A 2024 wrist injury interrupted her progress, but the WTA reported in June 2026 that she had been working her way back.

Elvina Kalieva

United States

Kalieva was born July 27, 2003 and plays right-handed. The structured feed lists her at No. 132, while the public WTA profile had not synchronized to that ranking, so the exact career-high date is left unset.
