Alexander Zverev claims tournament organisers are deliberately slowing down courts to favour the world’s top two Carlos Alcaraz and Jannik Sinner.

The world No 3 overcame an injury scare to beat Valentin Royer 6-4 6-4 at the Shanghai Masters but then voiced his displeasure with the way he felt the sport was heading.

“I hate when it’s the same, to be honest,” he said in his on-court interview.

“I think the tournament directors are going towards that direction because, obviously, they want Jannik and Carlos to do well every tournament and that’s what they prefer.

“Nowadays, you can play almost the same way on every surface. I don’t like it, I’m not a fan of it.

“I think tennis needs different game styles, tennis needs a little bit of variety and I think we’re lacking that right now.”

Zverev had to be treated on court for a toe injury when serving for the match at 5-4 in the second set but it did not halt his progress.

“I landed funny on my toe and after that I could barely do a step, so we’ll see what it is,” he added.

“We will see if I will ever be healthy this year again, because it’s been a struggle but I’m happy to be through.”

Sky Sports have contacted the ATP for comment.

Federer unhappy with court speeds

In September, Roger Federer appeared on the ‘Served With Andy Roddick’ podcast during the Laver Cup where he also called out organisers for using court speeds to help Alcaraz and Sinner.

“We need to have not only fast courts, but what we would want to see is Alcaraz or Sinner figure it out on lightning fast courts and then have the same match on super slow courts and see how that matches up,” said the 20-time Grand Slam champion.

“It’s because the tournament directors have allowed with the ball speed and the court speed that every week is basically the same. And that’s why you can just go from winning, French, Wimbledon, US Open, and just play the same way.”

Nick Kyrgios has also spoken about surface speeds in previous seasons, saying: “I’d like to see more variety. It’s good to play on [fast] courts like these, where aggressive tennis gets rewarded a little bit more.

“I want to see some bang-bang, one-two tennis-and a lot of those Federer fans still out there want to see that too. I loved watching that Federer one-two.”

Speaking before the start of the 2024 US Open, tournament director Stacey Allaster explained the surface speed at Flushing Meadows. “We aim for the court pace rating to be medium fast.” That can by anywhere from 41-44. The average court pace index [CPI] is 42.

“It’s where we like it to be at the start of the tournament so that as we ease into it, it gets closer to the end. We know that the speed of court gives it that right balance with the style of play – it’s been successful.”

The Shanghai Masters surface has seen a significant speed decrease, with reports showing a drop in its CPI from the 40-41 range in previous years to 32.9 in 2025, making the courts noticeably slower than they used to be.

British No 2 Cameron Norrie edged out Arthur Cazaux 6-3 0-6 7-6 (7-5) to reach the third round in Shanghai.

World No 7 Alex de Minaur beat Argentinan Camilo Ugo Carabelli 6-4 6-2 in 88 minutes, while Stefanos Tsitsipas withdrew with a leg injury before his scheduled match with Czech qualifier Dalibor Svrcina.
