The US Open is the first grand slam tournament to trial the innovation, with a clock on the scoreboard counting down the time taken by players between points during qualifying.
"I have gone deep with them in previous Grand Slams", said Zverev, who is looking to add a major title to his ever-fattening resume. Remarkably, the elder Williams won her two titles in NY in 2000 and 2001, and was last No1 more than 15 years ago, yet she is the only woman this year to have reached two Major finals. Andy Murray, 3. Roger Federer, 4. "I know you want to hear the other way that I would love to play with him".
"I think that's not possible for a great show. I think that's the way".
Simona Halep, now ranked #2 among the female players in the world, will face Sharapova in that opening round.
It was the first time Federer won a match against Nadal in a Grand Slam event since the 2007 Wimbledon final. She further stated that "This is a decision, of course, from the tournament.this is all actually I can say". I think it all depends on the day, as well. We'll find out when they play each other on Monday. We have our work cut out there.
KYLE EDMUND v Robin Haase (4pm United Kingdom time): Britain's No 2, who made the 4th round here a year ago, takes on the often flaky 32nd seed.
For the 137th time, the U.S. Open will be played, showcasing the finest tennis players the world has to offer.
Nadal has a winning record of 13-2 on clay and 8-5 on outdoor hard courts, while Federer leads the indoor hard courts 5-1 and 2-1 on grass.
If Federer can overcome Tiafoe, Mikhail Youzhny is his likely second-round opponent while veteran Feliciano Lopez could await in the third round before a fourth-round blockbuster with 14th seed Nick Kyrgios, who meets fellow Aussie John Millman.
"It s something that probably you and we don t expect to have that much success, but here we are", Nadal said. I am not that way. I will stay with Simona still again. "I think there is a lot of great, American women playing at the moment, and I think there is lots of opportunities". But I haven't seen any great results. Is true we played in all [other] Grand Slam finals. The Russian has missed the event due to injuries in 2008, 2013, 2015 and a year ago she was not able to compete because of the suspension. Her wayward form-not a single win over a top-20 player this season-will not encourage, either. One question that both players faced had to do with #Maria Sharapova and the wild card that she received into the main draw of Flushing Meadows. At around 20/1 she is not expected to contend but she can never be ruled out in big events. Maybe some players have just had enough of playing hurt and told just themselves, 'When I come back I just want to be 100 percent'. The only saving grace is that Sharapova has suffered injury problems since her return from a doping ban, and arrives having played only one match on hard courts: She retired after her opener in Stanford. The French Open denied her a wildcard and she missed Wimbledon with a thigh injury.
In the women's draw, Czech top seed Karolina Pliskova starts against Poland's Magda Linette and could face Russian eighth seed Svetlana Kuznetsova in the quarter-finals and Ukrainian fourth seed Elina Svitolina in the semi-finals. I'm not quite sure I would pick her. According to Halep, she has "had very tough draws every time nearly". Obviously Roger and Rafa are the biggest favourites still.
The 2014 U.S. Open champion, Marin Cilic, has been sidelined by a foot blister and also hasn't played since Wimbledon but he plans to give it a go at the Open.
After beating Williams to win the French Open last year, Muguruza struggled to adapt to her new-found status, but this year's Wimbledon triumph over Venus Williams has been taken smoothly in her long stride.
HEATHER WATSON v Alize Cornet (4pm): Channel Islander will have to produce one of her season's best efforts to pip world No 47 from France.
