Polina Kudermetova overcame a slow start to defeat Oleksandra Oliynykova 3-6, 7-6(1), 6-4 in the Charleston Round of 64 on March 31, 2026. After dropping the opening set, Kudermetova dominated the second-set tiebreak 7-1 before closing out the decider, edging Oliynykova 112-109 in total points won.
The match turned decisively in the second-set tiebreak, where Kudermetova’s composure under pressure contrasted sharply with Oliynykova’s inability to capitalize on superior serve percentages. Despite landing 74% of first serves compared to Kudermetova’s 61%, Oliynykova won just 56% of first-serve points — a marginal edge that proved insufficient when momentum shifted. Kudermetova’s advantage on second serves (46% to 38%) became the key differentiator, allowing her to weather Oliynykova’s early aggression.
The Russian closed out the match by taking the third set 6-4, her hard court winning percentage now standing at .700 across her career. She advances to the Round of 32, where her recent form — including a semifinal run in Merida — suggests she’ll pose a threat to higher-seeded opponents.
Key Takeaways
- Kudermetova’s second-serve effectiveness (46% vs. 38%) proved decisive in a match separated by just three total points, allowing her to hold serve despite landing only 61% of first deliveries.
- The second-set tiebreak swung the match conclusively — Kudermetova’s 7-1 dominance erased Oliynykova’s first-set momentum and exposed cracks in the Ukrainian’s mental game under pressure.
- Oliynykova committed six double faults despite serving at 74% on first serves, a troubling inconsistency that matched her recent averages of 22 unforced errors per match and undermined her cleaner serve mechanics.
- Kudermetova hit four aces, nearly double her hard court average of 2.3, while maintaining her characteristic resilience — she’s now won seven of nine hard court matches dating back to Merida and Seoul.
Player Analysis
Polina Kudermetova
Kudermetova’s comeback credentials were on full display. After losing the first set 3-6, she showed the same grit that carried her past Stojanovic in Merida (5-7, 6-4, 6-3) and into a semifinal there. Her ability to raise her level in the second-set tiebreak — winning it 7-1 — demonstrated the composure that’s become her trademark on hard courts, where she now boasts a .700 winning percentage. The serve wasn’t pretty (61% first serves, four double faults), but her 57% win rate on first serves and 46% on second serves outpaced Oliynykova when it mattered.
What’s most impressive is how Kudermetova navigated a match where she won just three more total points than her opponent. She picked her moments to attack second serves and dominated the only tiebreak, showing tactical maturity beyond her years. With four aces — well above her 2.3 hard court average — she demonstrated an ability to find free points when her percentage serving faltered.
Oleksandra Oliynykova
Oliynykova’s performance encapsulated the frustration of playing better tennis for stretches without closing out the victory. She served at 74% on first deliveries and took the opening set convincingly, yet won only 56% of first-serve points — a conversion rate that betrayed defensive vulnerabilities once rallies extended. Her six double faults, triple Kudermetova’s ace count, reflected the same error-prone tendencies that have haunted her recent matches (averaging 22 unforced errors per contest).
The second-set tiebreak exposed her Achilles’ heel: an inability to maintain aggressive shotmaking under duress. After winning 7-1 in the breaker, Kudermetova seized control of the decider. Oliynykova’s 38% second-serve points won tells the story of a player who couldn’t punish weaker deliveries, ultimately costing her a winnable match despite holding statistical edges in serve placement and total first-serve percentage.
