Valentin Vacherot, Monaco, won with 2–1 in sets after Holger Rune got cramp and could hardly move in the third set.
Also the day before yesterday, the 22-year-old Dane had major problems with the heat in China.
Do you want players to die on the court? he said to an official when he received treatment from a doctor and physiotherapist.
Holger Rune, 22, won the tournament in Stockholm 2022. He is ranked eleven in the world and will be the tournament's top name along with the Norwegian Casper Ruud, ranked twelve.
"I really look forward to playing in Stockholm again. It's always special to compete close to home and the atmosphere in the Kungliga Tennishallen is fantastic", says Rune in a press release.
