Suspected stomach flu is raging in the ATP tour tournament in Acapulco, Mexico.
No fewer than five players have withdrawn, including the Dane Holger Rune and the Norwegian Casper Ruud.
Rune's mother and agent Aneke Rune confirms to Danish TV2 that her son has been affected.
Several other players have also been affected. Tommy Paul, among others, also had to withdraw for the same reason. We have been informed that the tournament has launched an investigation, says Aneke Rune.
Casper Ruud on Instagram:
"I regret that I had to withdraw tonight. I had hoped to get over the stomach problems I felt yesterday".
