Garbine Muguruza was unable to hide her disappointment after she crashed out in the second round of Wimbledon in just 59 minutes on Thursday.
Muguruza, who reached the final last year, looked sluggish throughout the match and paid the ultimate price as she was beaten 3-6, 2-6 by Slovakian qualifier Jana Cepelova.
The 22-year-old came into WImbledon having won her maiden grand slam title at Roland Garros last month, but she was crestfallen not to have cleared the second hurdle.
“It’s tough, my energy was missing and I felt empty, a bit sick,” Muguruza told reporters. “But she played with no fear, was trying a lot of stuff, and I have to be prepared for that.
“Every time you step on court now, people are loose and they want to beat you so much. They don’t have anything to lose.
“I’m not surprised, because these things happen, and I need to learn to deal with it. But that is part of it [being at the top]. Opponents want to beat you more. But I like being up there at the top and this is normal.
“It is not that I feel pressure, more that there are expectations. I am experiencing a lot of things so fast. I have been through a lot of stages and it is only half the year.
“Perhaps I need to rest more to be ready, not to practise 10 hours a day. I have to try to avoid these kind of moments.”
Cepelova was delighted to have progressed to the third round and is starting to develop a knack of knocking over top-ranked players, having ousted third seed Simona Halep in the first round of the tournament last year.
“I like playing the champions on the big courts,” she said. “I had such good memories from [beating Halep] last year so I stepped out on court with confidence.
“I believed in myself for every point, every game. I like to play on grass and feel good after going through qualifying. I try to mix up my game, to change the shots.”
