A new generation looking to shake up the established order on the ATP

A new generation is looking to shake up the established order on the ATP Tour, but doesn't seem sure if it can do it.

Going into Wimbledon, Roger Federer, Rafael Nadal and Novak Djokovic have captured every Grand Slam since the 2016 US Open, which was won by Stan Wawrinka. All the Grand Slam champions on tour are now in their thirties.

Stefanos Tsitsipas would like that to change, saying, "It would give it a little bit of variety, something different to these guys."

But it won't be easy, according to the 20-year-old, who wants to be the one to break through but also called on his age group to step up. "We are responsible as the new generation to work hard to come up with something new and our best games to beat them. Some don’t want to take the responsibility," he said.

Tsitsipas has now joined 22-year-old Alexander Zverev among the top 10, and both have scored wins against members of the Top 3 at ATP or Grand Slam events. Among his age group, Tsitsipas also named Felix Auger-Aliassime, Denis Shapovalov, Taylor Fritz, Alex de Minaur, Frances Tiafoe as others who could contend for big titles.

But Nick Kyrgios, who is slightly older at 24 but has wins against Federer, Nadal and Djokovic, questions whether they currently have the game to win in best-of-five encounters at the Slams.

"I'm not sure if we give them too much respect. I just don't know if the younger guys are good enough to beat them in five sets," he said. "I don't think anyone will ever beat Rafa at the French while he is healthy, the court is just too suited to his game style. At Wimbledon, it's going to be tough to beat Novak or Federer in five sets."

There was agreement from 23-year-old Daniil Medvedev, who said the consistency of the Top 3 sets them apart.

"Every Grand Slam they are there and nearly every time they are finals or semifinals and me at this moment I don’t know how they do it. I really want to know why. Yeah, I hope one day we start beating them," he said.

All three players are currently competing at the ATP grass-court event at Queen's.
