With a Grand Slam breakthrough last week at Flushing Meadows, it looks like China might finally have a new champion on its hands.

His name? Wu Yibing. His latest claim to fame? Winning the 2017 US Open boys’ singles and doubles titles and reaching No.1 in the junior rankings. With no time to celebrate, the 17-year-old hopped on a plane to the ATP Challenger stop in Shanghai, showing little signs of slowing down as he looks to make the transition from juniors to pros.

Not long after touching down on home soil following just a few hours of rest, Wu picked up where he left off in New York with a surprising 6-3, 7-6(3) win over second-seeded Canadian Peter Polansky, who himself is coming off a fine summer in North America that included three ATP Challenger Tour finals.

Wu, who hails from Hangzhou just a few hours south of Shanghai, recognises the immediate impact of his US Open triumph. “I think it was a great experience for all the Chinese tennis players and [Chinese] associations,” said Wu. “We showed the world that we can do it for boys’ and men’s players also.”

With the exception of the year-end ITF Junior Masters in Chengdu, the Chinese teenager’s focus now shifts to the professional circuit, where he hopes his junior success will translate.

“I think it’s about the rhythm and how the players are thinking about the matches,” said Wu on the biggest difference in playing the pros. “They [are more] tough mentally and [have] more experience about how to win the match. About the technique… I think I am ready already.”

And Wu has reason to be confident in his game: In addition to his decorated junior resume, the foundations of his game are well set to develop into tangible threats at the ATP level. He’s quick on his feet, solid on the forehand wing, and generates exceptional racquet head speed on his backhand, a shot that cuts through the court and changes direction with ease.

Incidentally, it’s not difficult to see why Wu cites Andy Murray as the player he models his game after. “I’m trying to learn something from him, they way he plays and how he thinks; how he defends, how he chooses good timing for offensive [shots]… I think I can learn a lot from him.”

Despite major tennis successes by Chinese women, including two-time Grand Slam champion Li Na, China has waited patiently for a male champion to rise to the occasion of being the face of tennis in a country with greater tradition in other sports.

“I think that it’s the best thing [ever],” said Wu when asked about the impact that Li had on tennis in China. “She’s the first one to give us hope; real hope that young players can get to that level.”

Wu, however, isn’t without his own successful Chinese predecessors: journeymen Wu Di and Zhang Ze have paved the way for a younger generation of Chinese players in men’s tennis following their recent ATP Challenger victories in Maui (2016, d. Edmund) and San Francisco (2017, d. Pospisil), respectively.

Yet as both Wu Di and Zhang could relate to, with great success comes immeasurable pressure, and Wu acknowledges the pressure that a nation of over 1.3 billion people can place on young, talented shoulders such as his own.

“I think we don’t need to [have] too [much] pressure to be the same like Li Na, but we have to try to be at that level and work harder every day. Sometimes when I lose I want to give up,” admits the 17-year-old, candidly. But looking forward to the rest of the season – where he hopes to finish in the Top 300 of the Emirates ATP Rankings – and to 2018, he knows quite simply what improvement he has to make.

“I have to keep my mind tough.”

Wu will put his toughness to the test next against Shuichi Sekiguchi in the second round of the Shanghai Challenger.

Rafael Nadal turned up the heat on rivals Roger Federer and Novak Djokovic in their domination of the ‘Big Titles’ leaderboard by winning his third US Open trophy – and 16^th major overall – last Sunday in New York.

In defeating Kevin Anderson to capture the final major of the season, Nadal earned his fourth ‘Big Title’ of 2017, having already won his 10th titles at Roland Garros and the Monte-Carlo Rolex Masters as well as his fifth Mutua Madrid Open. The Spaniard now has a combined 46 ‘Big Titles’ — a collection of Grand Slams, Masters 1000 events and Nitto ATP Finals — putting him one behind Novak Djokovic’s 47 and within five of leader Roger Federer, who holds 51.

Djokovic still has the best conversion rate, capturing one ‘Big Title’ for every 3.4 events played. But Nadal is close behind with a ratio of 3.5. Djokovic and Nadal share the record for 30 Masters 1000 titles won; Federer has 26 Masters 1000s titles.

Current and Former Champions’ Big Titles Won (Records Since 1990)

 * Becker’s four other Grand Slam titles came before 1990.
** Edberg’s three other Grand Slam titles came before 1990.

Earlier this year Nadal qualified for the Nitto ATP Finals for the 13^th consecutive season, yet surprisingly he has never captured the title at the season finale. Victory in London from 12-19 November would also likely clinch for Nadal the year-end No. 1 Emirates ATP Ranking for the fourth time (2008, 2010, 2013). He currently leads the effective two-man race for the honour with five-time year-end No. 1 Federer, with whom he has shared this year’s four Grand Slam titles.

Federer qualified for the Nitto ATP Finals for the 15^th time after winning his eighth Wimbledon crown in July, which followed his Australian Open triumph in January. He also added ‘Big Titles’ at ATP World Tour Masters 1000 tournaments in Indian Wells and Miami, winning the ‘Sunshine Double’ for the third time in his career.

Nadal still has plenty to play for in 2017. He has never won the three ‘Big Titles’ still on the table this season – the Shanghai Rolex Masters, the Rolex Paris Masters and the Nitto ATP Finals. He was the beaten finalist at the season finale in 2010 (l. to Federer) and 2013 (l. to Djokovic).

Federer has won the Nitto ATP Finals a record six times, most recently in 2011, but has a more modest record in Shanghai and Paris, winning both tournaments just once.

Stefanos Tsitsipas capped a perfect week on the clay of Genova, Italy, claiming his maiden ATP Challenger Tour title on Sunday.

The 19 year old did not drop a set en route to becoming just the third player from Greece to lift a Challenger trophy. He joins countrymen Konstantinos Economidis and Vasilis Mazarakis.

Tsitsipas’ victory marks the 11th time a teenager has tasted victory on the circuit this year and second of the week, following Felix Auger-Aliassime’s title in Sevilla on Saturday. He rises to a career-high No. 120 in the Emirates ATP Rankings and moves up 11 spots in the Emirates ATP Race To Milan, to the 16th position.

Tsitsipas blogged about the breakthrough victory and spoke to ATPWorldTour.com…

Congratulations Stefanos on winning your first Challenger title. How did it feel to be standing with the trophy?
It was pretty special and something I’ve been dreaming about for a long time. It was a relief for me at the end. I was super happy and everyone on my team was happy. I brought a lot of happiness to people who were supporting me, throughout the whole tournament. They gave me a lot of positive energy and that helped a lot.

You did not drop a set this week. What was the key for you?
It was unusual. To not drop a set is rare and difficult to achieve. My serve was working very well throughout the week. I felt very comfortable with it. I was actually not going to play the Challenger, because it was right after the US Open finished and I wanted a rest. The last second I decided to play and it turned out to be a good decision.

You are just the third player from Greece to win a Challenger title. What does that mean to you for your country?
I am very happy to know this fact. And I am 100 per cent sure that it will inspire other kids in my country. It makes me happy, but I am going to keep working and it’s not the end of it.

Can’t thank enough my parents, siblings and friends for showing support and love. My first @ATPChallenger is dedicated to all of you!

Having lost two finals in Morocco last year, what did you take from those experiences into Sunday’s final in Genova?
It made me stronger for sure. It made me realize my mistakes from those two finals. I was ready for this one in Genova and I was more calm on the court. I handled the situation a bit better.

You’ve had some great wins and tough losses in the past year. How have you remained confident?
I know where my level is. I know I am one of these good NextGen players who can do well here. I never lost hope. I did have some good wins and tough losses this year, but my family and my team are always encouraging me. It has been working well. They are very supportive. There are a lot of people around me, but I don’t feel pressure. It makes you realize how important you are, to have a big team around you and it’s something good. I’m lucky to have them.

Really happy holding my first @ATPChallenger ?! It was definitely a great week! Thank you #Genova ??! pic.twitter.com/1VmYSPuHw8

You are up to No. 120 in the Emirates ATP Rankings. Has cracking the Top 100 been a goal for you this year?
Yes, that’s right. I set this goal at the beginning of the year. I hope to achieve it and I hope to be competing at the main draw of the Australian Open next year. I’m close and 20 spots is a matter of a few tournaments and some extra concentration. It’s motivation for me and my team. It’s going to come for sure. One extra push at a time.

How has the recent success of other teenagers, particularly Denis Shapovalov and Andrey Rublev, driven you?
For sure it has. I saw what Shapovalov did a few weeks ago in Montreal and it inspired me so much. It made me realize that nothing is impossible. He’s a year younger than me, so it’s insane what he did. It makes it even more special.

What were your impressions on the tournament in Genova – the 2014 Challenger of the Year?
It was a very good tournament. I had a lot of positive energy from it. The hotel was really nice and the club was perfect with a really big centre court. It’s something rare for a Challenger. I saw it was voted as the best Challenger of the Year. I was playing in front of a lot of people from the beginning of the week. Everything was perfect.

Lastly, what are your goals for the rest of the year?
I would say to win another Challenger. That would bring me closer to my goal of Top 100. I aim for one more Challenger title. I will probably go to China after the [ATP World Tour] tournament in Metz.
