Taylor Fritz and Casper Ruud will both be part of this year’s Stockholm Open.
Last year, the Stockholm Open was won by Casper Ruud, who beat Ugo Humbert in the final to win the ATP 250 tournament.
However, perhaps the biggest story from the 2025 tournament in the Swedish capital was former world number four Holger Rune suffering an Achilles rupture, which kept him out of action for nearly a year.
Rune is set to return to Stockholm this year, as he hopes to make better memories at the tournament he won in 2022, and he will also have to adapt to the ATP trialling a new rule.
If you were in charge of tennis, what is the first rule you would change?
The Stockholm Open will have the balls change more frequently this year
Tennis balls have been a big topic of conversation in recent years, with the changing of balls at different tournaments being linked by some to the growing number of wrist injuries within the sport.
Currently, the rules state that within matches, tennis balls change after the first seven games of the match, and then every seven games after that.
The ATP Tour is now trialling something different, starting at the Stockholm Open, with the balls changing after the first seven games and every seven games after that.
This is something that will be exclusive to the singles main draw, with both doubles and qualifying sticking to the standard rules.
The Stockholm Open is one of the final tournaments on the 2026 ATP calendar, getting underway from November 8. The ATP 250 event will feature the likes of Fritz, Alejandro Davidovich Fokina, Francisco Cerundolo, Alexander Bublik, as well as Ruud and Rune, all of whom will have to adapt to the new ball change trial.
