Casper Ruud has called for end to the ‘reckless behaviour’ on the ATP in the wake of incidents involving Nick Kyrgios and Alexander Zverev.

“I think it needs to stop,” Ruud told the Ruud Talk vodcast.

“This has been two three cases now in within a month. So it’s reckless behaviour in a way.

“It’s not something I wish to see, but at the same time, it kind of brings attention to the sport just in a negative way.

“I think the punishment is tough to say what is fair and what is not that they do get big fines, but for some of these players doesn’t seem like it matters. So it’s tough to say what we can do about it.

“I mean, majority of players, they don’t do these things, but the way it’s looking, it can look like a big, big accident or incident can occur at any time.

“So let’s see, I think they have been getting some fines and some meetings probably with the board and the guys in the ATP who are deciding in the end.”

Zverev was kicked out of the Mexican Open in February after a rant against the chair umpire and then hitting the official’s chair with his racquet.

Kyrgios was fined after incidents at the Indian Wells Open and Miami Open.

And the Aussie had another run-in with an umpire in Houston last week.
