Mira Andreeva Upsets Jennis Tjhen to Join Sabalenka in Cincinnati Fourth Round

Mira Andreeva, the tournament’s fifth seed, secured a place in the Cincinnati Open’s fourth round after a hard‑fought 1‑hour‑42‑minute victory over 32nd seed Jennis Tjhen. Andreeva triumphed 6‑1, 7‑6(5), showcasing a blend of power and consistency that left her opponent scrambling.

The win pairs Andreeva with Aryna Sabalenka, who earlier dispatched Wang Xinyu 6‑1, 6‑3. Both players now look ahead to a potential clash with tenth seed Marta Kostyuk, a fellow regular on the tour. Kostyuk holds a 2‑1 advantage in their head‑to‑head record, but Andreeva previously eliminated her in the Roland Garros semi‑finals.

Andreeva’s run in Cincinnati follows a quarter‑final appearance at the same event in 2024 and a breakthrough Grand Slam victory at Roland Garros earlier in 2024, her first major title.

Defending champion Coco Gauff also advanced, beating N. Lee 6‑1, 7‑6(3). Gauff’s victory marks her 36th fourth‑round appearance at a WTA 1000 tournament, reinforcing her status as one of the tour’s most consistent performers.

In addition to Sabalenka’s 50th WTA 1000 win, the tournament features seasoned campaigners such as Caroline Pliskova, Elena Svitolina and Iga Swiatek, all of whom have amassed substantial numbers of fourth‑round appearances at this level.

The competition in Cincinnati remains fierce, with players eyeing valuable ranking points and the prestige of a deep run at one of the sport’s premier hard‑court events.
