Konta vows to take positives from her shock early Aussie exit
Johanna Konta insisted her Australian Open loss to lucky loser Bernarda Pera was not a "massive catastrophe".
The ninth seed had been tipped as one of the contenders for the title after reaching the semi-finals and quarter-finals in the last two years.
Konta looked in good form in her opening win over Madison Brengle, but struggled to find her game in very hot conditions at Melbourne Park and came up against an inspired opponent, who claimed a 6-4 7-5 victory.
Konta said: "She played very inspired and I didn't do as much as I wanted. In the points I did okay, I stayed quite strong, but I don't think I did enough with my service games and my returns.
"It's a bit frustrating, but I'm still taking good stuff from this. I don't feel it's a massive catastrophe. I play every event to be there until the end, so I don't want to be going home this early.
"But in terms of building myself up and playing the way I want, I'll keep moving forward."
Wimbledon champion Garbine Muguruza was upset by Hsieh Su-wei, the third seed slumping to a 7-6 (7-1) 6-4 defeat.
Hsieh opened a 5-2 lead in the first set and, though Muguruza forced a tie-break, the player from Chinese Taipei took it.
Muguruza then broke Hsieh when she served for the match and saved a match point at 3-5, but two more arrived and the World No.88 took her chance.
