Angelique Kerber crashed out of the Sydney International in what was a surprising second round defeat by the Russian teenager, Daria Kasatkina in what proved a day of upsets at the pre-Australian Open warm-up event.
It was not so easy, but I will try to forget the match as soon as I can.
The world number one and Australian Open defending champion, was dumped out after 93-minutes, 7-6(5) 6-2 in what were sweltering conditions.
"I made too many mistakes and I was not actually feeling the ball, because the balls are flying here a little bit different than in Brisbane," the German said after committing 41 unforced errors. "So it was not so easy, but I will try to forget the match as soon as I can.
"I will go in the next few days to Melbourne, and I will try to get ready there, trying to get the positive energy from last year."
The 19-year-old Russian, ranked 26, underlined her huge potential with a confident performance following up her close match with French Open champion Garbine Muguruza last week when she was one point away from victory.
"Difficult to explain because I beat the No. 1 in the world and it doesn’t happen every day. I think I got some confidence," Kasatkina commented.
The Russian teenager will now play BritainÈs number one Jo Konta who served her way to a comfortable 6-1 6-3 win over AustraliaÈs Dari Gavrilova,
"I’m just happy I have accumulated a few matches already under my belt in the first few weeks of the season," Konta said.
Joining Kerber in defeat on a day of upsets, were defending champion Svetlana Kuznetsova and last yearÈs finalist, Dominika Cibulkova.
World number nine Kuznetsova went out to Russian compatriot Anastasia Pavlyuchenkova, Sam StosursÈ conquerors in the previous round, 7-5 6-3 while CanadaÈs Eugenie Bouchard continued her return to form with a 6-4 6-3 win over the sixth-ranked Cibulkova.
Ninth-seeded Italian Roberta Vinci was another seed to fall, losing 6-2 6-3 to veteran Czech player Barbora Strycova who will now take on the seventh seeded Caroline Wozniacki who ousted Yulia Putintseva 6-0 7-5
