Sabalenka overcomes serving struggles to beat Muchova in WTA Finals opener

Aryna Sabalenka opened her WTA Finals campaign with a 7-6 (7-2), 7-5 victory over Karolina Muchova, recovering from a break down in each set to secure her first group-stage win. BBC Sport reported that the world number two overcame an uneven serving performance and spells of frustration to start her bid for a first title at the season-ending event.

Watch the highlights:

Muchova put herself in position to take the opening set, breaking first and later serving for it. Sabalenka responded to the early break immediately, while errors from the Czech player helped take the set into a tie-break. Sabalenka won that decider 7-2, turning a difficult opening stretch into a one-set advantage against the Wimbledon runner-up.

The second set remained unsettled, with five breaks of serve before Sabalenka finally closed out the match. She was unable to finish it on her first attempt at serving for victory but succeeded on the second. Her forehand became more effective as the contest developed, even as her serve continued to cause problems.

Sabalenka finished with seven double faults and four aces. She landed 59% of her first serves and won 33 of the 44 points played behind them. Speaking to Sky Sports, she attributed some of the serving difficulty to changing sun and shade, explaining that the conditions required adjustments to her toss and sometimes affected her ability to see while serving.

The victory came against a particularly awkward opponent: according to the BBC, Muchova was the only player in the field with a winning career head-to-head record against Sabalenka. This is Sabalenka's sixth appearance at the Finals. World number one Elena Rybakina withdrew on the eve of the competition, while Sabalenka had already won the Indian Wells title on these courts in March.

Sabalenka arrived after winning only one of her three matches during the Asian swing and then taking a break. Her most recent title came in Miami in March. For the first season since 2022, she has not won a Grand Slam singles title, having lost both the Australian Open and US Open finals to Rybakina. The opening victory gives her a successful start to her remaining pursuit of the Finals trophy.
