Teodora Kostovic has taken a fast route from junior No. 4 to Grand Slam tennis
Teodora Kostovic finished 2024 outside the Top 800, then accelerated through the professional levels. She won her first title at W75 Kursumlijska Banja in 2025 and the W100 Amstetten trophy in July 2026, lifting her to a career-high No. 146. Between those victories, the Serbian qualified for her first Grand Slam main draw at Wimbledon and drew world No. 1 Aryna Sabalenka. Kostovic also reached No. 4 in the junior rankings and made the 2024 Wimbledon junior quarterfinals, evidence that her senior rise followed an established junior pathway rather than appearing from nowhere.
