It’s not the first time Cruz has shown off his talents on a world stage.

The teenager received a wildcard entry to the Australian Open 2024 Junior Championships, with his dad helping him warm up the morning of the match training on Show court 3 – the same court where Lleyton also made his main match debut.

“Just unbelievably proud, to be honest,” Lleyton Hewitt said to WWOS prior to the match.

“Just some great memories coming back of me playing here. He’s been around the traps, but he’s worked extremely hard to get this opportunity. He is playing well.”
