Sabalenka defeats Muchova in a tightly contested WTA Finals opener

World No. 2 Aryna Sabalenka opened her WTA Finals campaign with a narrow win over Karolina Muchova, prevailing 7‑6 (7‑2), 7‑5 in the first group‑two match. The Belarusian rallied from a break down in each set to secure the victory, marking her sixth appearance at the season‑ending event.

Sabalenka’s performance was marked by a mix of resilience and inconsistency. She recorded seven double faults and four aces, while landing 59 % of her first serves and winning 33 of the 44 points she started with her serve. The player acknowledged the challenging conditions, citing the shifting sun and shade that forced her to adjust her toss and serve approach.

The win keeps Sabalenka in contention for her first WTA Finals title, especially after world No. 1 Elena Rybakina withdrew on the eve of the tournament. With the Russian player’s exit, Sabalenka entered the event as a leading contender, having previously captured the Indian Wells title in March.

Sabalenka’s opponent, Karolina Muchova, a Wimbledon runner‑up, was unable to maintain a consistent level throughout the match. While both players displayed moments of high quality, Sabalenka’s forehand grew stronger as the contest progressed, ultimately tipping the balance in her favour.

The match concluded the opening day of the WTA Finals, which also featured French Open champion Mirra Andreeva defeating Elina Svitolina 6‑4, 6‑0. The tournament continues to showcase the year’s top women’s tennis talent as they vie for the prestigious season‑ending title.
