Aryna Sabalenka opened her WTA Finals campaign with a hard-fought victory over Karolina Muchova, prevailing 7-6 (7-2) 7-5 despite battling an inconsistent serve and her own frustrations on court. The world number two, who reached the season-ending final in 2022 and 2025, is pursuing her first WTA Finals title in her sixth appearance at the event. According to BBC Sport, Sabalenka's path to the trophy became clearer when rival and world number one Elena Rybakina withdrew on the eve of the competition, making Sabalenka arguably the favourite to triumph.
The opening group two match saw neither player performing consistently at their peak. Sabalenka recovered from a break down in both sets to secure the win, though her serve proved problematic throughout. She produced seven double faults against four aces, landing 59% of her first serves and winning 33 of 44 points behind her delivery.
"It was a bit tricky with the sun [and] with the shade," Sabalenka told Sky Sports. "Sometimes I had to adjust my toss, sometimes I had to serve blind, but it's all part of the game."
Despite the serve difficulties, Sabalenka's forehand grew increasingly potent as the match progressed. According to Tennis Now, she struck 22 winners and committed 18 unforced errors while breaking Muchova's serve five times. The victory proved significant in multiple ways: Reuters reported that Sabalenka recorded her 300th ace of the season during the match, becoming the second woman to reach that mark in 2026 after Rybakina. Additionally, the win tied her head-to-head record with Muchova at 3–3.
Sabalenka's Challenging Season
By her own elevated standards, Sabalenka has experienced an unusual campaign. For the first time since 2022, she failed to capture a Grand Slam singles title, losing both the Australian Open and US Open finals to Rybakina. Her most recent title came in Miami in March, when she defeated Rybakina in a thrilling Indian Wells final that saw her save a match point. Since that victory, she won only one of three matches during the Asian swing before taking a break ahead of the season-ending finals.
Muchova presented a particularly tricky opponent, being the only player at the WTA Finals with a winning head-to-head record against Sabalenka entering their match. The Czech player claimed the opening break of the first set, but Sabalenka responded immediately by breaking straight back—a pattern that would define the entire contest. Muchova served for the first set but a succession of errors forced the match into a tie-break, where further mistakes from the Czech player handed Sabalenka the opener.
The second set proved equally volatile, featuring five breaks of serve across its duration. Sabalenka ultimately served out the match on her second attempt to secure the victory. According to WTA Tennis, Muchova had entered the match having won every tiebreak she had played in 2026, but Sabalenka's win gave her a tour-leading 13 tiebreak victories this season.
Andreeva Dominates in Contrasting Performance
In stark contrast to Sabalenka's tight affair, French Open champion Mirra Andreeva delivered a commanding display, defeating Ukraine's Elina Svitolina 6-4 6-0 later on Monday. The teenage Russian proved ruthless against the wayward Svitolina, reeling off seven consecutive games and relying on her impressive backhand to control rallies.
Andreeva's defensive prowess was equally notable, as she saved all six break points she faced—four of which came in the final game. She accumulated nine winners against 12 unforced errors in a 77-minute victory. The result was particularly significant given that Andreeva defeated Sabalenka in the 2025 Indian Wells final, establishing herself as a rising threat in women's tennis.
Other Results and Upcoming Matches
In other tennis action, Britain's Cameron Norrie advanced at the Stockholm Open by defeating Australian James Duckworth 7-5 6-0 to reach the second round. Norrie will next face top seed Taylor Fritz as he continues his preparations for this month's Davis Cup Finals. Fellow Briton Toby Samuel also progressed at the same event, claiming a 6-3 6-2 victory over Leo Borg, son of 11-time Grand Slam singles champion Bjorn.
What Happens Next
Sabalenka's remaining Group 2 round-robin matches are scheduled for November 11 and 13, with the semifinals set for November 14 and the championship match on November 15. Her opening victory positions her well in the pursuit of her first WTA Finals title, though she will need to improve her serving consistency and maintain the form her forehand displayed in the latter stages of her match against Muchova.
