Sabalenka and Pegula Advance as Noskova Survives Kostyuk Thriller | US Open 2026 Day 8 Roundup
US Open 2026 Day 8 Roundup
Aryna Sabalenka extended her US Open winning streak to 17 matches, Jessica Pegula ended Sorana Cirstea’s final Grand Slam appearance and Linda Noskova survived six match points of her own before completing a dramatic victory over Marta Kostyuk.
The US Open 2026 Day 8 roundup also saw Emma Navarro defeat Anna Kalinskaya, creating an all-American quarterfinal against Pegula.
Sabalenka Passes Townsend’s Unconventional Test
Aryna Sabalenka defeated Taylor Townsend 6–4, 6–3 in one hour and 15 minutes to reach her sixth consecutive US Open quarterfinal.
The opening set was much less orderly than the scoreline suggests.
Seven of its first 10 games went against serve as Townsend’s left-handed angles, aggressive returns and willingness to move forward prevented Sabalenka from establishing her usual first-strike rhythm.
Sabalenka secured the match’s first service hold for 4–2, but Townsend immediately remained involved by breaking when the defending champion attempted to serve out the set.
The world No. 1 responded with a forceful forehand winner to break again and take the opener.
Townsend created one more genuine opportunity when she moved ahead 3–1 in the second set. Sabalenka’s response was emphatic: she conceded only five further points while sweeping the final five games.
Townsend won only eight of her 20 approaches to the net. Her attacking style created uncertainty, but Sabalenka increasingly found passing lanes and forced her to play difficult volleys.
The victory extends Sabalenka’s US Open winning streak to 17 matches. She has reached the quarterfinals without dropping a set:
- Camila Osorio: 6–4, 6–3
- Polina Iatcenko: 6–1, 6–1
- Kamilla Rakhimova: 6–3, 6–4
- Taylor Townsend: 6–4, 6–3
Her bid for a third consecutive US Open title now meets its first fellow Grand Slam champion: Wimbledon winner Linda Noskova. Sabalenka leads their head-to-head series 2–0.

Noskova Finally Closes the Door on Kostyuk
Linda Noskova defeated Marta Kostyuk 7–5, 5–7, 6–4 after two hours and 27 minutes.
The final score only partially captures the tension.
Noskova led by a set and 5–3 before earning her first two match points while serving at 5–4. Kostyuk saved both, broke serve and won four consecutive games to force a deciding set.
The Ukrainian then erased another break deficit in the third and saved three more match points.
Nearly an hour passed between Noskova’s first opportunity to finish the contest and the moment she finally converted her sixth match point.
Very little separated them statistically. Noskova won 105 points to Kostyuk’s 104, but her strength against Kostyuk’s second serve ultimately provided the narrow advantage.
The victory carries additional significance because Noskova also defeated Kostyuk in the Wimbledon semifinals before winning her first major title.
Noskova has now won 11 consecutive Grand Slam matches and reached her first US Open quarterfinal. She is also the youngest Czech woman to reach this stage in New York since Daja Bedáňová in 2001.
Against Sabalenka, however, Noskova will have less room for hesitation. Six unconverted match points did not cost her against Kostyuk; similar uncertainty against the defending champion probably would.

Pegula Ends Cirstea’s Final US Open Run
Jessica Pegula defeated Sorana Cirstea 6–3, 6–4 to reach the US Open quarterfinals.
Neither player established immediate control through serve. The opening set contained several exchanges of breaks before Pegula converted her fifth set point.
The second followed a similar pattern, but Pegula found the decisive break and prevented Cirstea from extending her final US Open appearance into another three-set contest.
It was a considerably cleaner day for Pegula after she recovered from a one-set deficit against Leylah Fernandez in the third round.
Her passage through the tournament now includes:
- Sofia Kenin: 6–1, 6–1
- Leylah Fernandez: 1–6, 6–4, 6–3
- Sorana Cirstea: 6–3, 6–4
Cirstea leaves New York at the end of one of the strongest late-career stretches on the tour.
The Romanian reached the fourth round in her final Grand Slam season and eliminated No. 19 seed Jasmine Paolini along the way. Pegula acknowledged afterward that Cirstea remained an exceptionally difficult opponent despite approaching retirement.
Pegula, the 2024 US Open finalist, will now face Emma Navarro in an all-American quarterfinal.

Navarro’s Patience Breaks Down Kalinskaya
Emma Navarro defeated Anna Kalinskaya 6–4, 6–2 in one hour and 21 minutes.
Kalinskaya had won both of their previous meetings, but Navarro reversed that pattern through consistency and superior control of the baseline exchanges.
The first set remained competitive before Navarro pulled away. Winning it changed the complexion of the match: she raced to a 5–1 advantage in the second set and did not allow Kalinskaya’s brief recovery to develop into a comeback.
The statistical contrast was revealing.
Kalinskaya produced 17 winners but committed 32 unforced errors. Navarro struck 15 winners while limiting herself to only 10 unforced errors.
Navarro did not need to overwhelm her opponent. She repeatedly extended rallies until Kalinskaya attempted too much.
The American returns to the US Open quarterfinals two years after reaching her first Grand Slam semifinal here. It is the fourth major quarterfinal of her career.
Her route has hardly been effortless. Navarro has conceded 40 games—the most among this year’s US Open quarterfinalists—but repeatedly found solutions when matches became complicated.

Pegula and Navarro Set Up All-American Quarterfinal
Jessica Pegula leads Emma Navarro 4–0 in their head-to-head series, including a victory in Cincinnati last month.
Their meeting will be the first all-American women’s singles quarterfinal at the US Open since Serena Williams defeated Venus Williams in 2015.
Pegula enters with the stronger serve, greater weight of shot and more experience at this stage. Navarro’s advantage lies in her ability to absorb pace, extend exchanges and expose impatience.
The matchup guarantees that an American woman will reach the semifinals.
For Pegula, anything short of another deep run would feel like an opportunity missed. Several dangerous players have already disappeared from her half, and she has reached the final and semifinal during the previous two editions.
Navarro has less pressure but must solve a matchup that has consistently favoured Pegula.

What the US Open 2026 Day 8 Roundup Told Us
Sabalenka remains the standard in the top half of the draw.
Townsend created the tactical disruption many expected, but Sabalenka recovered from the early exchanges and played her strongest tennis precisely when the upset appeared possible.
Noskova survived a much less comfortable passage. Her inability to close the match efficiently is a warning, yet winning after five failed match points also showed considerable emotional resistance.
Pegula and Navarro followed simpler routes.
Pegula’s controlled victory restored stability after her difficult match against Fernandez. Navarro once again demonstrated that consistency can be an attacking weapon when an opponent supplies 32 unforced errors.
The confirmed quarterfinals from this half are:
- Aryna Sabalenka vs. Linda Noskova
- Jessica Pegula vs. Emma Navarro
Sabalenka–Noskova brings together the two most recent Wimbledon and US Open champions. Pegula–Navarro guarantees American representation in the semifinals.
