Defending champion Rafael Nadal on Sunday reached the US Open quarter-finals for the eighth time where he will face Dominic Thiem, one of only three men to defeat him in 2018.
In the women’s section, six-time champion Serena Williams survived a spirited challenge from unseeded Kaia Kanepi to triumph 6-0, 4-6, 6-3 and reach the quarter-finals.
World number one Nadal saw off a battling Nikoloz Basilashvili, the first Georgian in a fourth round in New York, 6-3, 6-3, 6-7 (6/8), 6-4.
It was world number 37 Basilashvili’s strength, however, which proved his undoing.
His 56 winners were erased by 59 unforced errors, three times as many as Nadal.
Elsewhere, Juan Martin del Potro, the 2009 champion, beat Borna Coric 6-4, 6-3, 6-1 to make the last-eight for a third successive year.
The third seeded Argentine will next face John Isner, the last American man standing, who defeated Milos Raonic 3-6, 6-3, 6-4, 3-6, 6-2, taking his tournament aces total past the 100-mark.
Thiem, who beat Nadal on clay in Madrid in the run-up to Paris, booked his place in the quarter-finals for the first time with a 7-5, 6-2, 7-6 (7/2) win over 2017 runner-up Kevin Anderson.
The ninth-seeded Austrian’s three other appearances in the last-eight of a Slam were all on Paris clay in 2016, 2017 and 2018.
Nadal leads their head-to-head 7-3 with all of their matches coming on clay courts, including in the final of Roland Garros in June when he captured an 11th French Open.
Meanwhile, Serena, the 23-time Grand Slam champion looked set to romp home when she seized the first set from Kanepi in just 18 minutes.
But the hard-hitting Estonian, who took out world number one Simona Halep in the first round, settled down in the second set, shaking off the partisan crowd in a jammed Arthur Ashe Stadium to push Williams the rest of the way.
Williams finished with 18 aces and 47 total winners. A couple of loose points gifted Kanepi a break in the first game of the second set, however, and she couldn’t get back on terms.
Williams booked a quarter-final date with Karolina Pliskova, the eighth-seeded Czech who beat Australian Ashleigh Barty 6-4, 6-4.
Pliskova defeated Williams in the semi-finals in New York in 2016.
Defending champion Sloane Stephens, the third seed, eased past Elise Mertens 6-3, 6-3 to book a quarter-final rematch with Latvian Anastasija Sevastova.
