This was the first time that Medvedev, who claimed the title in 2023, had won the same tournament twice. His 22 previous titles had come at different events.
“That’s what is crazy about it. I never did it in any city in the world, and the first time I do it, it’s a walkover,” he told the ATP Tour website.

His representative told the New York Times, external they were trying to establish how Medvedev could travel to California for next week’s Indian Wells tournament after the United Arab Emirates “partially and temporarily” closed its airspace.
