Casper Ruud lashes out at Madrid fans: "There are unwritten rules about what can and can't be done."

Casper Ruud booked his place in the 2025 Mutua Madrid Open final on Friday in a semifinal match in which, despite the victory, he was far from happy with the home crowd and their behavior . He emphasized this in the press conference afterward, where he complained about the whistling from the crowd during his service calls.

"I felt at first that the encouragement was directed at Francisco (Cerúndolo), and that's not illegal," he emphasized, always courteous, before explaining that it was a matter of the "rhythm" of the match . In fact, Ruud very politely addressed the referee to try to control the situation, as he explained in the press conference.

"If I'm about to serve and they cheer again and all that... What's the protocol? How many times is a fan or someone in the crowd allowed to harass a player? I asked the umpire that question. If I were given the opportunity to redo the first serve, would it be redone? Probably not," he complained.

"I think they should put more pressure on the fans who are there to heckle or boo," Ruud added.

"Francisco hasn't done anything wrong, and I don't want to be an idiot toward him. I understand that fans can cheer on whoever they want, but in tennis, there are unwritten rules about what you can and can't do as a spectator . When someone is too annoying, it's going too far," he insisted.

Casper Ruud takes a chance against Jack Draper

The Norwegian, who was once the world's second-ranked player, will play in his third Masters 1000 final in Madrid. " Returning to a Masters 1000 final is a great feeling . You don't play for these titles every day. I've been to two finals and lost, so I hope the third time's the charm," he said.
