Olivia Rogowska must hope for a discretionary invitation into the main draw of the Australian Open after the top seed suffered a shock defeat at the hands of unranked teenager Kaylah McPhee at the wildcard play-offs on Tuesday.

Rogowska, who reached a career-high world ranking of 102 last year but has since fallen to 275, was no match for the 17-year-old Queenslander, who advanced to the quarter-finals with a 6-3 6-2 first-round win at Melbourne Park.

The 24-year-old Victorian has progressed past the first round of the Australian Open just twice in seven attempts after being granted wildcard entry and now faces a nervous wait to she if she will be offered another.

“I guess I put too much pressure on myself – being the No. 1 seed I was expecting to win the whole thing,” Rogowska told AAP.

“She played very well – I wasn’t expecting that kind of tennis. I haven’t played such (high-intensity) tennis like that for a while and I guess my confidence is a bit low.

“I haven’t had many matches … nothing really clicked today. I played well in streaks but didn’t play well in important points.”

On an extraordinary day of upsets in the women’s draw, all seeded players bar Arina Rodionova (2) and Storm Sanders (6) were bundled out of the tournament that awards an Australian Open wildcard to the male and female winners.

Queenslander Naiktha Bains and Victorian Destanee Aiava both progressed in three sets in the early matches, with Abbie Myers, Belinda Woolcock and Maddison Inglis the other winners.

On Monday, top seed James Duckworth and Melburnian Marinko Matosevic were among the players to win through to the quarter-final stage in men’s action, which continues on Wednesday.
