The 19-year-old is making her main draw debut at Melbourne Park but proved too good for Kontaveit, seen by many as a serious title contender after a breakout 2021.

The Estonian captured four titles in two months last year before ending runner-up at the WTA Finals to Garbine Muguruza, but struggled against Tauson.

She won just 55% of her first serves and made 27 unforced errors for a disappointing end to her tournament.

In contrast, Tauson won 73% of her first serves and kept the error count down to just 13.

“I felt so good out here and I could hear a lot of people cheering and that gave me so much confidence and I played a very good match,” said Tauson, at a career-high ranking of 39.

“I really didn’t go into this match with the winning thought, I was just so happy to be here and Anett has been playing so good for the last couple of months. I was just going in to see where my level was at and here I am.”

Tauson signalled her potential by making finals last year in Luxembourg and Lyon.
