Previously named in Australia’s squads against Germany in 2012 and Slovakia in 2016, Duckworth made his first ATP Tour semi-final in Pune, India, in early February before winning a Challenger event in Bengaluru a week later.

‘‘I’ve been playing some pretty good tennis so I’m really excited to get the call-up,’’ Duckworth said. ‘‘We are all playing a mix of singles and doubles at training and, apart from John, could all play that [doubles match] so there’s a few options. We’re all playing pretty well.

‘‘Practice matches will be taken into consideration, and also form over the last few weeks and what the coaches are thinking match-up wise.’’

Brazil’s team will include exciting teen Thiago Seyboth Wild, who won an ATP title last month in Chile, and will be anchored by world No. 82 Thiago Monteiro.

Experienced pair Bruno Soares and Marcelo Melo are ranked in the top 25 in doubles.

Seyboth Wild became the youngest Brazilian title-winner and the first teenager to lift a tour-level trophy since De Minaur triumphed in 2019 in Sydney. He leapt 69 places to world No. 113 on the back of his win over world No. 38 Casper Ruud, of Norway, in the final.
