Leylah Fernandez battled for three hours and three minutes in Ningbo's second round on October 21, beating qualifier Aliaksandra Sasnovich 7–5, 6–7 (tie-break 3–7), 6–3 to reach the quarter-finals. The same day, Marta Kostyuk's injury retirement advanced Ekaterina Alexandrova and secured Karolína Muchová the final WTA Finals singles place.
From 3–5 in the opener to a fifth quarter-final this season
WTA's report recorded Fernandez recovering from 3–5 to take the first set 7–5. She lost the second-set tie-break before winning the decider 6–3. It was her fifth tour quarter-final this season and her first in Ningbo.
Fernandez now leads Sasnovich 3–2 overall and has won all three hard-court meetings. In her on-court interview, she credited positivity and calm, describing a difficult match but an enjoyable atmosphere. She hoped to sustain fuller focus afterward, identifying match-long concentration as the next improvement after three sets.
One retirement changes both Ningbo and year-end qualification
Alexandrova took the opening set 6–4 in the other second-round match before Kostyuk retired. The official Ningbo draw lists a right-wrist injury and retirement at 0–0 in set two. Alexandrova reached a second consecutive Ningbo quarter-final and will face Fernandez, who beat her in three sets in Wuhan last week.
Their accumulated time in Ningbo's first two rounds differs markedly. WTA listed Fernandez at five hours 52 minutes and Alexandrova at one hour 53 minutes, a difference of three hours 59 minutes. Alexandrova still leads their overall head-to-head 3–2, and the last three meetings all went to three sets. Shorter court time this week and previous results need separate treatment.
| Advancing player | Second-round opponent | Confirmed result |
|---|---|---|
| Fernandez | Sasnovich | 7–5, 6–7 (tie-break 3–7), 6–3 |
| Alexandrova | Kostyuk | 6–4, opponent retired at 0–0 in set two |
Muchová qualifies a second time, preparing for her first appearance
With Kostyuk unable to keep pursuing the Ningbo title, WTA confirmed Muchová as the eighth and final singles qualifier. She qualified in 2023 but withdrew injured, making this her second qualification and prospective first actual Finals appearance. Qualification counts and participation counts differ.
The Indian Wells Finals singles field comprises Rybakina, Sabalenka, Mirra Andreeva, Nosková, Gauff, Pegula, Svitolina and Muchová. Muchová won on hard courts in Doha and grass in Bad Homburg this year and reached the Stuttgart clay final and Wimbledon final. The same WTA announcement confirmed two doubles pairs, but one doubles berth remained open: a complete singles lineup did not settle every tournament place.
INKA SPORTS analysis: Same quarter-final round, different routes and consequences
Fernandez played three sets in both rounds, while Alexandrova's second round ended after one set when her opponent retired. They reach the same stage with very different accumulated workloads. The three-hour, 59-minute difference describes expenditure already incurred this week, not a direct conversion into next-round win probability. Their recent three-set encounters also show that the matchup still needs to be resolved on court.
Finals qualification followed a separate clear sequence: Kostyuk left the Ningbo contest, the final singles berth was settled, and Muchová benefited. Combining the result, retirement status and qualification announcement explains why a match that ended at 0–0 in the second set could affect a year-end event elsewhere.
Conclusion
The day confirmed a Ningbo quarter-final pairing and completed the WTA Finals singles lineup. Fernandez continued after a long battle, Alexandrova advanced following injury retirement and Muchová gained the chance for a first actual Finals appearance. Court time shows differing workloads, while their three consecutive recent three-set meetings provide a specific next-match storyline.
