Elina Svitolina admitted she was "not really in a good place" after losing in straight sets to Magda Linette in the second round at Wimbledon.
Third seed Svitolina became the latest big name in the women's draw to exit early at SW19, going down 6-3 6-4 on Thursday.
Linette claimed her first win over a top-10 player in some style, too, the world number 44 needing just 65 minutes to come out on top, aided by converting three of nine break-point chances she created against an out-of-sorts opponent.
For Svitolina, the result comes as she deals with a tough period in her career. The Ukrainian exited in the last 16 at Eastbourne ahead of the third grand slam of the season, while she was knocked out in the third round at the French Open.
"Mentally, I was not really in a good place. When you play a grand slam it's a different kind of pressure. Sometimes it's tough to handle but it's part of the job - it is part of the grand slam," she said after the defeat on grass.
"You have to try to be strong, try to be good to yourself and try to overcome the fears, the difficulties. Today probably I was not fresh mentally to do that.
"Right now I wouldn't say it's very smooth times in my career. It's a tough time, but I have been in these situations in my career a few times."

Svitolina's exit means just four of the top eight seeds are left standing. Sofia Kenin and Bianca Andreescu both went out in the opening round, while Serena Williams was forced to retire due to injury in the first set against Aliaksandra Sasnovich.
However, top seed Ashleigh Barty remains in the running, the Australian seeing off Anna Blinkova in straight sets on Centre Court.
While her serve faltered, Barty had too much power as she clinched a 6-4 6-3 result that sets up a meeting with Katerina Siniakova in the third round.
