Second seed Rafael Nadal wasted no time getting down to business on Sunday at the US Open, racing through the opening set 6-3 against South Korean qualifier Hyeon Chung in their third-round clash.

A backhand sent just wide from Chung at 2-3 gave the Spaniard the first break of the match. The slight advantage was all the three-time US Open champion needed and he fired an ace to take the early lead.

Nadal leads Chung 2-0 in their FedEx ATP Head2Head series and has won all five sets they’ve played. The winner of this match faces No. 14 seed John Isner of the United States or former US Open champion Marin Cilic of Croatia, the No. 22 seed.

Rafael Nadal is known for always being on the go. But after receiving a walkover in his second round at the US Open, the Spaniard has been forced to sit without playing a live point since Tuesday. The second seed will be eager to hit the court once again as he headlines third-round action on Saturday, joined by sixth-seeded German Alexander Zverev, No. 13 seed Gael Monfils of France and No. 28 seed Nick Kyrgios of Australia.

Nadal takes on South Korean Hyeon Chung, who is enjoying a successful comeback after missing five months this season with a back injury. Chung, the inaugural Next Gen ATP Finals champion in 2017, scored back-to-back five-set wins this week to reach the third round. He won the first tournament of his comeback earlier this month at an ATP Challenger Tour event in Chengdu. Having beaten Novak Djokovic and Alexander Zverev en route to the semi-finals of the 2018 Australian Open, Chung knows what it takes to excel at Grand Slams.

But what he’s yet to excel at is mastering Nadal. The Spaniard leads their FedEx ATP Head2Head rivalry 2-0 and won all four sets they’ve played. Nadal will also be the fresher of the two for their showdown. Chung has spent a minute under seven hours on court this week, in addition to his three qualifying matches last week, while Nadal required just over two hours to defeat Aussie John Millman on Tuesday. He hasn’t been in action since then due to Aussie Thanasi Kokkinakis withdrawing from their second-round match with a shoulder injury, but did manage to save the day for a young fan off the court on Friday.

Zverev will look for a shorter stay on court when he meets Slovenian Aljaz Bedene, who is competing in the third round of the US Open for the first time. The sixth seed added to his reputation as a fifth-set expert, prevailing in consecutive five-setters this week against Moldovan Radu Albot and #NextGenATP American Frances Tiafoe. Zverev holds a 3-0 lead against Bedene in their FedEx ATP Head2Head rivalry, including a convincing win at this year’s Australian Open, and will need to replicate that effort to remain fresh for the second week.

“I’m just trying to regain my full confidence. It’s about going match by match for me. It’s about doing the best I can for now,” said Zverev before the tournament started. “It’s the first time in a few years where I’m not a favorite in any way at a Grand Slam and it takes some pressure off, as well. It’s a different mindset for me now.”

Two of the flashiest players on tour square off for the first time when Monfils takes on #NextGenATP Canadian Denis Shapovalov. The Frenchman is back in the Top 15 for the first time in two years after outstanding results this season that include a title in Rotterdam (d. Wawrinka) and semi-final finish at the Masters 1000 event in Montreal. Meanwhile, Shapovalov has been finding his form again after beginning to work last week with former Top 10 player Mikhail Youzhny. The 20-year-old reached his first semi-final since March in Winston-Salem and hasn’t dropped a set so far this week.

“I’m a big fan of his. He’s been so exciting to watch from when I was super young. I’ve always seen him come out with crazy points, crazy hot shots. He’s so athletic on the court. I think he’s one of the best athletes in the world in any sport,” Shapovalov said of Monfils. “He can really do everything. He can play aggressive, he can stay in the rallies, he’s got a big serve. It’s going to be a tough match.”

Kyrgios closes out the evening session against Russian Andrey Rublev. Both men have been in top form during the North American hard-court swing, with Kyrgios prevailing at the Citi Open (d. Medvedev) and Rublev defeating Roger Federer to reach his first ATP Masters 1000 quarter-final in Cincinnati. The US Open holds extra weight for Rublev as the venue where he announced his arrival on Tour, coming through qualifying to reach the quarter-finals in 2017, while Kyrgios looks to reach the second week at this event for the first time.

“He’s a young, fearless player who has been playing really well the last couple weeks,” Kyrgios said. Obviously he had that win over Roger. He plays big from both sides. He’s a great player. He’s going to have a great future.”

Other notable matches on Saturday include No. 14 seed John Isner of the United States taking on former US Open champion and No. 22 seed Marin Cilic of Croatia, while #NextGenATP Aussie Alexei Popyrin meets No. 24 seed Matteo Berrettini of Italy.

As the clock struck midnight, Daniil Medvedev wrapped up Day 5 at the US Open with a highly entertaining victory over Feliciano Lopez.

A physical clash from first ball to last, Medvedev outlasted Lopez 7-6(1), 4-6, 7-6(7), 6-4, after three hours and 19 minutes of hard-hitting tennis. The World No. 5 equalled his best result at a Grand Slam, having also reached the Round of 16 at the Australian Open this year. It marks his first second-week appearance in New York.

It was a war of attrition as Medvedev fought past Lopez in a roller-coaster affair that concluded at 12:04am on Louis Armstrong Stadium. He fired 55 winners, including 27 aces, while surviving 85 net approaches by the Madrid native.

The drama was palpable on Armstrong and the New York crowd got firmly behind Lopez as the match wore on. An agitated Medvedev had the home fans against him as the match got underway, but the Russian fed off the high-octane atmosphere.

Despite squandering a 5-3 lead and dropping the opening set in a tie-break, Lopez immediately snatched the second set with a break in the first game. The Spaniard would draw level just 38 minutes later, raising his arms in the air and calling on the New York faithful to rally behind him. You could cut the tension with a knife as the third set entered a tie-break, with the veteran saving a set point with a lunging volley. But two points later, Medvedev finally got the better of Lopez to seize the set.

The Russian would not look back from there, sprinting to a 3-2 lead in the fourth set with a perfect baseline-to-baseline backhand lob. And he would seal the victory on his first match point with a backhand winner.

Medvedev closes out the month of August with a staggering 17-2 record, also including final appearances at the Citi Open in Washington, Coupe Rogers in Montreal and title at the Western & Southern Open in Cincinnati. He owns a tour-leading 47 match wins – and 33 on hard courts – this year.

Meanwhile, on Grandstand, Dominik Koepfer extended his magical run another day. Koepfer stunned 17th seed Nikoloz Basilashvili 6-3, 7-6(5), 4-6, 6-1 for his first Top 20 win and first appearance in the second week of a Grand Slam.

The German became just the second qualifier to reach the Round of 16 at the US Open since 2009, joining Denis Shapovalov (2017). Just a year ago, Koepfer was sitting at No. 243 in the ATP Rankings and he is now projected to crack the Top 100 with his deep run in New York.

“It’s unbelievable,” said Koepfer after the match. “It’s my first time here and I’ve been here for two weeks now. Same dinner spots before every match, but I like winning so I guess we have to keep it going.

“I thought I just competed really well for four sets. I fought for every ball and every point. I guess it paid off in the end.”

Under the tutelage of former pro Rhyne Williams, Koepfer is soaring. He claimed his lone ATP Challenger Tour title on the grass of Ilkley in June, before reaching the second round of Wimbledon. Now, he has taken it one step further at the US Open.
