WTA Indian Wells Round-Up Day Six | Swiatek advances comfortably, Pegula rallies as Andreeva falls

The third round of the WTA Indian Wells produced several notable results as Jessica Pegula, Iga Swiatek and Elina Svitolina progressed to the Round of 16, while Katerina Siniakova delivered one of the biggest surprises of the day by eliminating defending champion Mirra Andreeva. Another upset came from Britain’s Sonay Kartal, who recovered from a set down to defeat Madison Keys and continue her impressive run in the California desert.

The results further shaped the latter stages of the draw, with Pegula continuing her consistent 2026 campaign and Swiatek maintaining strong form as one of the tournament favourites. Meanwhile, Siniakova’s victory removed the reigning champion from the field, while Kartal’s win over Keys marked one of the most significant victories of her career as the event moves toward the second week.

Iga Swiatek recovered from an early deficit to defeat Maria Sakkari 6-3, 6-2 and secure her place in the fourth round at Indian Wells. The world No. 2 gradually imposed her consistency from the baseline after a difficult opening phase against the Greek.

Sakkari began the match strongly, breaking serve in the opening game and briefly controlling the early exchanges. However, Swiatek quickly settled into the match and began dictating rallies with deeper groundstrokes and aggressive returning. After recovering the break, the Pole found her rhythm and won five of the next six games to take the opening set. Her ability to pressure Sakkari’s serve proved decisive, particularly when attacking second deliveries and forcing the Greek into defensive positions.

The second set followed a similar pattern. Sakkari briefly broke back to level the set at 2-2, but Swiatek responded immediately by regaining the advantage and maintaining control through consistent baseline play. The Pole eventually secured a double break and closed out the match comfortably.

Statistically, Swiatek dominated Sakkari’s second serve, winning 79% of those points while maintaining solid efficiency behind her own delivery. With the victory, Swiatek advances to the fourth round where she will face 13th seed Karolina Muchova in one of the most anticipated matchups of the next stage.

Jessica Pegula recovered from a difficult start to defeat Jelena Ostapenko 4-6, 6-3, 6-2 and advance to the fourth round at Indian Wells. The American gradually imposed her consistency after a challenging opening set against the aggressive Latvian.

Ostapenko began the match strongly, applying early pressure from the baseline and securing a crucial break midway through the first set. Pegula struggled initially to contain the Latvian’s attacking style, and Ostapenko closed out the set after maintaining control of the rallies during the closing games.

The momentum began to shift during the second set as Pegula adjusted her return positioning and extended rallies. After trailing early, the American produced a decisive surge by winning the final five games of the set to level the match and force a deciding third.

In the final set, Pegula carried that momentum forward. After an early exchange of breaks, the world No. 5 gradually took control with her consistency from the baseline and improved serving. She closed out the victory by winning five of the last six games.

Statistically, Pegula dominated key moments on return, winning 42% of Ostapenko’s first-serve points and 58% of her second-serve points. She also produced 11 aces and won 74% of points behind her first serve. With the victory, Pegula advances to the Round of 16 where she will face Belinda Bencic for a place in the quarter-finals.

Katerina Siniakova produced one of the most notable results of the session by defeating defending champion Mirra Andreeva 4-6, 7-6, 6-3 in a physically demanding contest lasting more than two and a half hours. Andreeva appeared in control early in the match. The 18-year-old recovered from a break deficit in the first set and won four consecutive games to secure the opener 6-4, continuing the strong form she had shown earlier in the tournament.

The second set proved significantly more competitive, with both players exchanging breaks as tension grew late in the set. The set was ultimately decided in a tie-break where Andreeva held a narrow lead before Siniakova won the final three points to force a deciding set.

The Czech carried that momentum into the third set. After several momentum swings early in the decider, Siniakova secured a crucial break to move ahead 5-3 and successfully served out the match.

The statistics reflected how tightly contested the match was, with both players winning exactly eight service games. Siniakova proved slightly more effective in the decisive moments, saving 20 of the 27 break points she faced. The victory marks Siniakova’s 12th career Top 10 win and eliminates the defending champion from the tournament.

Sonay Kartal delivered one of the most surprising results of the round by defeating world No. 15 Madison Keys 2-6, 6-2, 6-3 to reach the fourth round. Keys appeared firmly in control during the opening set, capitalising on several inconsistencies from Kartal’s serve and breaking three times to secure a comfortable 6-2 lead.

However, the momentum shifted quickly in the second set. Kartal raised her level on return and began extending rallies more effectively. The Brit secured an early break and later added another to force a deciding set.

The final set remained competitive early, with both players holding serve through the opening games. The decisive moment arrived at 3-3 when Kartal broke serve before maintaining her composure to close out the match by winning the final three games.

Kartal’s ability to apply pressure on Keys’ serve proved crucial. She won 41% of first-serve return points and 50% on the American’s second serve. With the victory, Kartal advances to the fourth round where she will face the winner of Elena Rybakina and Marta Kostyuk.

Elina Svitolina produced a composed performance to defeat Ashlyn Krueger 6-4, 6-2 and advance to the Round of 16. The Ukrainian secured the opening set through consistent baseline play, winning a high percentage of points behind her first serve while limiting unforced errors during key moments.

After taking the first set, Svitolina quickly gained control of the match by winning five consecutive games across the second set. Her return game proved decisive, repeatedly neutralising Krueger’s serve and forcing longer rallies. Svitolina finished the match having won 84% of points behind her first serve and 45% of return points on Krueger’s first delivery. The victory sends Svitolina into the fourth round, where she will face Katerina Siniakova.

Karolina Muchova advanced comfortably to the Round of 16 with a 6-0, 6-3 victory over Antonia Ruzic. The Czech dominated the opening set, breaking three times and winning the majority of baseline exchanges to secure the set without dropping a game.

Ruzic showed greater resistance in the second set but was unable to maintain consistent pressure on Muchova’s serve. The 13th seed eventually secured another break to close out the match in straight sets. Muchova won 86% of points behind her first serve and converted several key return opportunities throughout the match. She will next face Iga Swiatek in the fourth round.

Belinda Bencic secured her place in the fourth round with a 6-2, 6-3 victory over Elise Mertens. The Swiss player established control early by breaking twice in the opening set and consistently pressuring Mertens’ serve. Her strong returning allowed her to dictate the tempo of the rallies.

Although Mertens briefly broke early in the second set, Bencic responded immediately and regained control. She eventually closed out the match on her serve after missing a couple of match points on return. Bencic finished the match winning 74% of points behind her first serve and nearly half of Mertens’ first-serve return points. She now advances to face Jessica Pegula for a place in the quarter-finals.

Elena Rybakina closed the final match of the day at Indian Wells with a hard-fought 6-4, 6-4 victory over Marta Kostyuk. The Kazakh found herself in trouble early in the second set but managed to turn the momentum around late on to seal her place in the fourth round.

The opening set remained tightly contested, with both players holding comfortably for long stretches. Rybakina eventually made the decisive move at 5-4, capitalising on a brief dip from Kostyuk to secure the lone break of the set and take the early advantage.

Kostyuk responded well at the start of the second set, immediately breaking and briefly taking control of the scoreboard. The Ukrainian looked set to push the match into a decider as she protected her lead through the middle stages of the set.

However, the momentum shifted late on as physical issues began to trouble Kostyuk. Rybakina raised her level at the crucial moment, dominating the closing stretch by winning 16 of the final 20 points. The 2026 Australian Open champion ultimately sealed the victory with authority to end the session in Tennis Paradise.
