Mirra Andreeva produced a remarkable turnaround against Aryna Sabalenka to become the second singles player to qualify for the 2026 WTA Finals semifinals, while Elina Svitolina kept her own qualification hopes alive with a three-set victory over Karolina Muchova.
Day 4 of the season-ending championships at Indian Wells belonged to Andreeva, who recovered from 4-1 down in the opening set to defeat Sabalenka 6-4, 6-0 in just 62 minutes.
The 19-year-old won the final 11 games of the match, becoming the youngest player to reach the WTA Finals semifinals since Caroline Wozniacki in 2009.
Earlier, Svitolina defeated Muchova 3-6, 6-2, 6-2, setting up a decisive final group match against Sabalenka.
Andreeva Wins 11 Consecutive Games to Stun Sabalenka
Mirra Andreeva’s second WTA Finals match looked to be heading in the wrong direction when Aryna Sabalenka raced to a 4-1 lead in the opening set.
Sabalenka had made the stronger start, breaking the teenager’s serve and appearing comfortable against an opponent she had defeated in four of their previous six meetings.
What followed was an extraordinary reversal.
Andreeva won the next 12 points to level the opening set at 4-4 before completing the comeback with three consecutive aces.
She carried that momentum into the second set, where Sabalenka was unable to win another game.
In total, Andreeva claimed the final 11 games and 45 of the last 55 points.
The teenager admitted that frustration had played a role in sparking her turnaround.
“I was angry. I was not very happy with how things went.”
Andreeva explained that she had channelled that frustration into her serving, allowing her to settle into the match and take control.
Despite the emphatic victory, she was reluctant to give herself a perfect score.
“I would give myself a good eight.”
The result secured Andreeva’s first WTA Finals semifinal appearance and continued an impressive tournament debut.
Having defeated Svitolina 6-4, 6-0 in her opening match, Andreeva became the first player in tournament history to win a 6-0 set in each of her first two WTA Finals matches.
She is also just the fifth teenager to reach the semifinals since the round-robin format was introduced in 2003, joining Maria Sharapova, Ana Ivanovic, Caroline Wozniacki and Coco Gauff.
For Sabalenka, the defeat was difficult to explain.
“She definitely played great tennis. For now, what can I say? Bravo.”
The World No. 2 remains in semifinal contention, but must now defeat Svitolina in her final group match.

Elina Svitolina kept her WTA Finals campaign alive with a determined 3-6, 6-2, 6-2 victory over Karolina Muchova.
The Ukrainian had suffered a convincing defeat to Andreeva in her opening match and appeared in danger of another loss when Muchova claimed the first set.
However, Svitolina gradually adjusted to the Czech’s variety, becoming more aggressive from the baseline and forcing her opponent into errors.
The turnaround was particularly significant given Muchova’s remarkable record when winning the opening set.
Before Wednesday, Muchova had won all 32 matches in which she had taken the first set during 2026.
Svitolina ended that streak.
“It was important just to try to find my game. I was really unhappy with the first set.”
The 2018 WTA Finals champion raised her level considerably in the second and third sets, conceding just four games across the final two sets.
She finished with 22 winners, including 17 across the final two sets, and secured her 11th career victory at the WTA Finals.
It was also her first victory at the tournament since 2019.
The result improved Svitolina’s three-set record this season to 19-5 and left her with one victory and one defeat in Group 2.
Muchova, meanwhile, has been eliminated after losing her opening two matches.

The Canadian-Brazilian partnership had lost to Guo and Mladenovic in the Wimbledon final earlier this season, but reversed that result in a closely contested match.
After claiming a tight opening set, Dabrowski and Stefani were taken to a deciding match tiebreak.
Guo and Mladenovic moved ahead 5-2, but Dabrowski and Stefani recovered to win eight consecutive points and complete the victory.
The result gave Dabrowski and Stefani their second group victory and secured their place in the semifinals.
The pair have enjoyed an outstanding 2026 season, winning six titles together, including WTA 1000 events in Dubai, Beijing and Wuhan.

After losing their opening match to Guo Hanyu and Kristina Mladenovic, the Taiwanese-Latvian partnership bounced back to improve their Group 1 record to 1-1.
The defeat leaves Mertens and Zhang without a victory from their opening two matches, eliminating them from semifinal contention.
