Iga Swiatek criticized the relentless tennis calendar on Sunday, with the former world No. 1 saying players should not be forced to compete in more than 20 tournaments a year to maintain their rankings.
Now ranked fourth in the world, Swiatek described being trapped in a system where she had to choose between representing her country and focusing on herself after she skipped Poland's Billie Jean King Cup qualifier in April.
"The scheduling is super intense. It's too intense. There's no point for us to play over 20 tournaments in a year," Swiatek told reporters when asked about the biggest challenge to players in terms of mental health. "Sometimes we need to sacrifice playing for your country because we need to keep up with playing these WTA 500s, for example, because we're going to get a zero in the ranking."
Swiatek has previously mentioned challenges presented by the tennis calendar, citing the mental health issue before last year's US Open and blaming a February loss on a lack of preparation.
"I think these kind of obligations and the rules about mandatory tournaments just put pressure on us," she said Sunday. "... I think people would still watch tennis, maybe even more, if we played less tournaments. The quality would be better."
The long tennis schedule was one of the cornerstones of the lawsuit filed by the Professional Tennis Players' Association against the sport's governing bodies in March after the union described it as "unsustainable."
Swiatek is the eighth seed at Wimbledon this year, and she faces Polina Kudermetova in the first round Tuesday.
The clay-court specialist with four French Open titles fell in the semifinals at Roland Garros this year, and she quickly switched her focus to grass, which has historically been her weakest surface.
She reached her first grass-court final Saturday at the Bad Homburg Open, where she was left in tears after losing to top seed Jessica Pegula, but Swiatek is happy with her improvement on grass as she comes to grips with the faster surface.
"It's not like a huge change. It's not like 180 degrees change. I wouldn't say now suddenly everything is perfect, because it's still a difficult surface. It's still tricky," Swiatek said. "Every year it feels like it's a little bit easier to get used to the surface, and then you have more time to just develop as a player."
