De Minaur Moves Past Wimbledon Loss
De Minaur made a separate reference to public reactions following a previous loss at Wimbledon.
"I don't think it was warranted, as much as a lot of people – myself included – wanted to make a big deal out of it," said de Minaur.
He explained that he quickly moved past the setback to prepare for upcoming events.
"It became a really big thing, but realistically, it took me a couple of days to get over it.
They were just the same feelings and emotions that any athlete has after a tough loss. Now, I'm feeling great," said de Minaur.
