Berrettini, 26, took to Instagram on Tuesday and wrote:
"I am heartbroken to announce that I need to withdraw from @wimbledon due to a positive COVID-19 test result.
I have had flu symptoms and been isolating the last few days. Despite symptoms not being severe, I decided it was important to take another test this morning to protect the health and safety of my fellow competitors and everyone else involved in the tournament.
I have no words to describe the extreme disappointed I feel. The dream is over for this year, but I will be back stronger."
The All England Club later confirmed the development.
We'll miss you, Matteo - come back stronger in 2023 💚 💜 pic.twitter.com/vEu9yAHGNP— Wimbledon (@Wimbledon) June 28, 2022
