Gadecki lives up to hype with big Open win

Mentored by retired reigning champion Ash Barty, Gadecki was making her main-draw debut at the Open after missing the entire summer last year after declining to get vaccinated against COVID-19.

That decision came after an unranked Gadecki had burst onto the international stage with a stunning victory over 2020 Australian Open champion Sofia Kenin at the 2021 Phillip Island Trophy event at Melbourne Park.

Gadecki backed up that breakthrough win with a rapid rise up the rankings under esteemed coach David Taylor, Samantha Stosur's long-time former ally and mentor of greats including Martina Hingis and Naomi Osaka.

While fans have had to wait to see Gadecki in action at her home grand slam, the 20-year-old certainly didn't disappoint after finally making her debut.

She seized the opening set against Kudermetova with the only break of the set, nailing a booming backhand down the line in the 12th game to draw rapturous applause from spectators on Court 8.

The adrenaline surge triggered a run of six straight games won for Gadecki as the young gun powered to her first grand slam triumph in 76 minutes.

"I actually can't believe it. Wow, I'm speechless," Gadecki beamed.

"It's such an amazing crowd, my home slam, my first-ever main-draw grand slam win. I mean, a girl can only dream."

Gadecki's reward, after crunching seven aces, 19 winnersand conceding only nine points on serve, is a second-round shot at exciting Ukrainian talent Marta Kostyuk on Wednesday.

Kostyuk, the world No.61, claimed the first seeded scalp of the tournament, eliminating 28th-seeded American Amanda Anisimova 6-3 6-4.

Five other Australians are in action later on day one, including fellow women's wildcards Storm Hunter and Talia Gibson.

Jason Kubler, John Millman and Rinky Hijikata lead the local charge in the men's singles on Monday.
