Khachanov survives Tien as Blockx reaches a US Open quarter-final

Karen Khachanov came through a five-set test with Learner Tien, while Alexander Blockx joined him in the last eight and the American quarter-final pairings took shape in New York.

The second week has produced a proper test of the men’s draw. Karen Khachanov needed five sets to get past Learner Tien, then Alexander Blockx followed him into the quarter-finals by beating 24th seed Francisco Cerundolo. The last-eight meeting will pit Khachanov’s experience against one of the tournament’s sharpest runs.

Khachanov outlasts Tien, Blockx keeps going Khachanov beat Tien 7-5, 4-6, 7-6(8-6), 6-1, 6-4. The deciding stretch came after Tien had levelled the match and taken the third-set tie-break deep; Khachanov then closed out the fourth and fifth sets to move through. Blockx took a different route to the same stage. The 28th seed beat Cerundolo 6-3, 4-6, 7-5, 7-5 and will face Khachanov in the quarter-finals. The official draw lists that match alongside Alexander Zverev against Botic van de Zandschulp, the other men’s quarter-final still to be scheduled.

Swiatek and Osaka leave the women’s draw Qinwen Zheng beat Iga Swiatek 7-5, 6-3, ending the Pole’s run in straight sets. Elena Rybakina also advanced in straight sets, beating Naomi Osaka 6-1, 6-4. That leaves Zheng and Rybakina together in a quarter-final, while Aryna Sabalenka faces Linda Noskova and Jessica Pegula meets Emma Navarro. Mirra Andreeva and Coco Gauff complete the other confirmed last-eight pairing after Andreeva beat Anastasia Potapova 5-7, 6-4, 6-3 and Gauff beat Iva Jovic 6-1, 6-4.

Two American quarter-finals on the schedule Frances Tiafoe and Alex Michelsen will meet on Arthur Ashe Stadium not before 1:00pm local time (6:00pm BST), after the 11:30am session opener between Sabalenka and Noskova. Ben Shelton then plays Carlos Alcaraz in the evening session, following the 7:00pm Pegula–Navarro match. The official order of play labels that second match as follows, rather than giving it a separate start time. That gives the United States three men in the quarter-finals, with Tiafoe–Michelsen guaranteeing one American place in the semi-finals and Shelton facing the defending champion.

British interest remains strongest in doubles Henry Patten and Harri Heliovaara, the top seeds, are scheduled first on Court 12 against Francisco Cabral and JJ Tracy at 11:00am local time (4:00pm BST). Julian Cash and Lloyd Glasspool also moved into the third round, beating Adam Pavlasek and Patrik Rikl 7-6(7-2), 6-4. Their next match against Kevin Krawietz and Tim Puetz follows the earlier Court 5 matches, with no separate start time given. Joe Salisbury and Rajeev Ram came through a tight second-round contest against Theo Arribage and Albano Olivetti, winning 6-7(2-7), 7-6(11-9), 6-4. They face wild cards Brandon Carpico and Nikita Samuel on Court 5 not before 4:00pm local time (9:00pm BST).
