Teen sensation Destanee Aiava has booked her spot in the women’s singles at next month’s Australian Open at the second attempt with a crushing win over Tammi Patterson in the wildcard playoff final.

The 17-year-old Aiava won 6-4 6-0 on Sunday against the third-seeded Patterson at Melbourne Park.

It came a week after Aiava was beaten by Jaimee Fourlis in the final of the Australian under-18 championship, with the winner of that match also guaranteed an Open wildcard.

“I came into it this week thinking that I’ll just go for it and I have nothing to lose,” said the second-seeded Aiava after seeing off the challenge of Patterson.

“If it’s a positive outcome then so be it, or negative, then that’s fine as well. And I’m young anyway, so there’s not really much expectation.”

Aiava woin the first 12 points of Sunday’s match to race to a 3-0 lead.

Patterson fought back to level at 3-3 before Aiava took command, claiming nine of the remaining 10 games.

“I knew I finished off the first set strong so I just wanted to to the same thing and keep building and building momentum and keep firing my shots with confidence,” she said.

“I was trying not to think about the prize at the end. I just wanted to go for it.”

Top seed Alex Bolt was playing No.2 Alex De Minaur in the men’s playoff final on Sunday.
