Iga Swiatek claims she 'didn't look good' on grass from her very first training session this summer after her Wimbledon exit.
Swiatek came into Wimbledon in incredible form and on the back of six successive tournament wins, including the French Open.
However, she lost out to Alize Cornet 6-4, 6-2 in the third round, bringing a 37-match winning streak to an end.
"In order to reverse an adverse situation you have to have a plan, know what you're playing at, and I didn't have it here," Swiatek admitted.
"I thought that thanks to the confidence with which I arrived, I was going to feel better on grass. I'm leaving a bit disappointed, but I hope to get along with grass one day.
"I'm usually hard on myself when I lose, but I knew this was coming and I had a feeling it would happen in this tournament.
"From the first training sessions I didn't look good. Maybe it would have been good to play more matches earlier [on grass], but after Roland Garros I felt like I needed a break."
Iga Swiatek was unusually passive in her groundstrokes against the impressive Cornet.
She later explained that it was a deliberate ploy to try to cut out the unforced errors. It worked to a degree, but it also ultimately cost her.
"I know I haven't played well," she said. "What has led me to success this season was being very aggressive on the court, looking for the point at all times and taking the initiative, but here I feel like I can't control the ball well."
"Today I started bad and decided to slow down my shots, at least not make as many unforced errors.
"What I ended up doing is pushing the ball, I gained some solidity, but my shots didn't hurt.
"I had been in the mentality of attacking, [but] it has been very difficult for me to play consistently without being too passive."
