Serena Williams won her first match, easily claiming a 6-4, 6-0 win first-round win that took just more than an hour. "It's such a good feeling to be back out here," said Williams, who improved to 18-0 in first-round matches at Flushing Meadows and 68-1 in openers at all Slams. "The first set was tight. It was my first back here in New York, so that wasn't the easiest. Once I got settled, I started doing what I'm trying to do in practice."

Day 1 U.S. Open Winners, Results Updates *Already, we've had a major upset on U.S. Open day 1, with No. 1 women's player Simona Halep becoming an upset victim. Halep was defeated by 44th-ranked Kaia Kanepi of Estonia 6-2 6-4. The match lasted 76 minutes. Halep won the French Open in June, but this is the second consecutive year she has lost in the first round of the U.S. Open. *U.S. player Jack Sock earned a win today. The No. 18-seeded American "snapped a seven-match losing streak in singles matches on tour with a 6-0, 7-6 (4), 6-2 victory over Guido Andreozzi of Argentina in the first round of the U.S. Open," according to the AP. *Venus Williams advanced to the second round, beating Svetlana Kuznetsova 6-3, 5-7, 6-3 in a matchup of past U.S. Open champions. Williams is the No. 16 seed.<doc-sep>TPN/Getty Images The second week of the 2018 U.S. Open gets under way on Monday at Flushing Meadows in New York, and two-time champion Novak Djokovic is in action at Arthur Ashe Stadium in the afternoon session. The No. 6 seed faces a fourth-round clash with Portugal's Joao Sousa, who he has beaten in all four of their previous meetings without dropping a set. America's Madison Keys kicks off the action at Arthur Ashe against Dominika Cibulkova in what should be a tight contest, while Kei Nishikori, Marin Cilic and David Goffin are all set to turn out at Louis Armstrong Stadium. Here is the schedule for Monday afternoon, per the tournament's official website: Arthur Ashe Stadium (Play begins noon ET, 5 p.m. BST) (14) Madison Keys vs. (29) Dominika Cibulkova Video Play Button Videos you might like (6) Novak Djokovic vs. Joao Sousa Louis Armstrong Stadium (Play begins 11 a.m. ET, 4 p.m. BST) (21) Kei Nishikori vs. Philipp Kohlschreiber (26) Aryna Sabalenka vs. (20) Naomi Osaka (7) Marin Cilic vs. (10) David Goffin TV Info: In the United States, ESPN (live stream at WatchESPN) and the Tennis Channel will provide coverage. For viewers in the UK, the matches will be streamed live on Amazon Prime. Djokovic, 31, triumphed in New York in 2011 and 2015 and has reached five other finals at Flushing Meadows. Since 2007, he has reached at least the semi-finals every time he has competed at the U.S. Open. He will confirm his place in this year's quarter-finals by beating Sousa, and there is little reason to suggest he won't continue his perfect record against the 29-year-old. Sarah Stier/Getty Images Sousa has never before made it to the fourth round at the U.S. Open, and he has played significantly more tennis at the 2018 tournament than Djokovic. His four-set defeat of Lucas Pouille in the third round ran to three hours, 38 minutes, and he played for more than three hours against Pablo Carreno Busta in the second round. It has not been plain sailing for Djokovic as he dropped sets in both of his opening rounds, but he has had an easier run of things than Sousa. The Serb downed Richard Gasquet in three sets in the third round in a fine performance, per Metro's George Bellshaw: Djokovic has struggled with injury in the last few seasons but is on his way back to his best, and his triumph at this year's Wimbledon moved him to 13 Grand Slam titles. There seems an inevitability about him meeting Roger Federer at the U.S. Open, with the two superstars set to come together in the quarter-finals, assuming they both win on Monday. No. 2 seed Federer takes on John Millman of Australia in the evening session on Monday, by which time Djokovic should have already sealed his place in the last eight.<doc-sep>For the first time in two years, tennis legend Serena Williams will return to the US Open tonight, when she will take on Magda Linette at the Arthur Ashe Stadium in Flushing, New York. The six-time US Open champion last played in the tournament in 2016, where she lost to runner-up Karolina Pliskova in the semifinals. The match begins tonight (August 27) at 7 p.m. ET, kicking off a First Round prime-time block that will air on ESPN2 until about 11 p.m. You can check out the tournament’s full broadcast schedule here.

Nadal's clash with David Ferrer proved to be underwhelming on Monday, as Ferrer pulled out of the match due to injury. It means Vasek Pospisil will be facing a well rested 17-time Grand Slam champion on Wednesday. Stephens was a routine winner in her opener against Evgeniya Rodina and will face a game opponent in the form of 21-year-old qualifier Anhelina Kalinina. Serena Williams is also scheduled to face Carina Witthoeft. Expect a number of these elite players to move through the gears on Wednesday. Here are the big matches to come, the details on where to re-watch the action and a look ahead at the standout tussles.

Holders Seek to Make Progress on Wednesday KENA BETANCUR/Getty Images The all-Spanish showdown between Nadal and Ferrer was expected to be one of the most interesting of the opening matches in the men's draw. However, those on Arthur Ashe were left disappointed as Ferrer pulled out after losing a tight first set. As relayed by Ava Wallace of the Washington Post, Nadal was full of praise for the veteran, who was playing in his final Grand Slam event: For Nadal, sentiment will go out of the window now, as he'll be taking the challenge posed by Pospisil seriously. That despite the fact the Canadian has never progressed beyond the second round at Flushing Meadows. Another player who'll be closely watched on Wednesday will be Andy Murray, as he made a winning return to Grand Slam tennis with a four-set victory over James Duckworth; after losing the first set, the 2012 U.S. Open winner improved as the match went on to progress. In the buildup to his next match, against talented veteran Fernando Verdasco, Murray spoke candidly about how much he's missed tennis at the highest level, per broadcaster Catherine Whittaker: Juan Martin del Potro is also worth keeping an eye on against America's Denis Kudla; the third seed demolished Kudla's compatriot Donald Young in the opening round. After two first-round exits in three of the major championships this year, Stephens would've been a little nervous about the first match in defence of her title on Monday. In the end, she played with the swagger of a Grand Slam winner, breezing past Rodina. Sarah Stier/Getty Images While there are a number of world-class performers in the women's draw, you sense Stephens will have to overcome Williams at some point if she's to win back-to-back U.S. Open titles. The Undefeated's Soraya Nadia McDonald was impressed with the vigour Williams performed with in her win over Magda Linette: Witthoeft has it in her to become an awkward opponent for the six-time U.S. Open champion, but Williams is a heavy favourite to progress into the third round. Two-time Grand Slam champion Garbine Muguruza will also be out to entertain the crowds and progress towards her first major final of 2018.<doc-sep>
Matthew Stockman/Getty Images Roger Federer and Novak Djokovic will headline Monday's play at the U.S. Open, as the second week gets under way at Flushing Meadows. Federer will be seeking to book his spot in the quarter-finals following an excellent display against Nick Kyrgios in the previous round and is the big favourite against Australia's John Millman. Djokovic is also expected to progress without too much fuss against Joao Sousa. Elsewhere, this side of the women's draw is wide open following a number of shocks. Maria Sharapova, who is looking for her first U.S. Open title for 12 years, goes up against Carla Suarez Navarro in what has the potential to be one of the matches of the day. Here is the broadcast information for Monday at Flushing Meadows, the schedule for the day and a preview of what's to come.

Monday Preview TPN/Getty Images Even though he's now 37 years old and hasn't triumphed at Flushing Meadows for a decade, it's always a treat to see Federer strutting his stuff at the Arthur Ashe Stadium. Against Kyrgios, the Swiss was at his imperious best again. While the Australian can be a dangerous opponent when he gets on a roll, Federer was able to absorb everything he had to offer and use his quality to race to a three-set win. The main talking point was an outrageous forehand winner around the net from Federer. Even his opponent was full of praise for the 20-time Grand Slam winner: If Federer showcases the same quality again, then Millman faces a major battle if he's to make it into the last eight. The same goes for Sousa, who will be out to spring a surprise against Djokovic. While the Serb wasn't at full tilt in wins over Marton Fucsovics and Tennys Sandgren, in the previous round against Richard Gasquet, he really did move through the gears to secure a three-set victory. In the past, the Portuguese hasn't fared particularly well against Djokovic either, per tennis journalist Jose Morgado: Still, the Wimbledon champion is expecting a challenging match. "He's a fighter, he's a grinder," he said, per BBC Sport. "He will not hand you the victory, you've got to earn it." While almost all of the pre-tournament favourites remain in contention in the men's draw at Flushing Meadows, a number of big names have been eliminated from the women's bracket. EDUARDO MUNOZ ALVAREZ/Getty Images It means Sharapova has an excellent chance of winning her first Grand Slam for the first time in four years. On her way to the last 16, the Russian has yet to drop a set and is playing some of her best tennis of the season. In addition, the 31-year-old is scheduled for one of the later starts. Per Stuart Fraser of The Times, she has an excellent record in this slot: Suarez Navarro has the talent to end that run, although she may be feeling a little jaded already at the tournament. All of the Spaniard's matches at the competition have been three-set contests up to this point. Madison Keys is in action first and will receive plenty of backing from the home supporters when she takes on Dominika Cibulkova, as the American seeks to better her runners-up finish from a year ago.
