Elina Svitolina’s Wimbledon could be compromised after the two-time semi-finalist pulled from this week’s WTA German tuneup in Bad Homburg with a hip injury.

The unfortunate timing leaves the Ukrainian just four days to try and get fit for Monday’s start of the grass-court major.

Svitolina won a Tuesday match over Liudmila Samsonova but later withdrew from an upcoming quarter-final against China’s Xinyu Wang in the last eight.

“Unfortunately I will be pulling out of my quarter-final match in Bad Homburg,” Svitolina posted on social media on Wednesday.

“Last night was a hard-fought victory but it took a little bit more than expected out of my body. So therefore, I need a few more days to recover.

“I wish all the best to all the players who are still competing and a lot of success to the tournament, and hopefully to see you all next year.”

The world No. 8  is dealing with a problem in her right hip.

Naomi Osaka managed a rare grass court win on Tuesday as the Japanese hardcourter left it late to start her pre-WImbledon build-up.

The four time grand Slam champion on cement in Melbourne and New York, has only this week on grass at the WTA Bad Homburg event to prepare for Monday’s start at the All England club.

Osaka has played the major only five times in her career and has never passed the third round.

But after defeating Elise Mertens 6-3, 6-3 to reach the quarter-finals, the 28-year-old has suddenly found growing confidence on the lawns.

“Honestly, it’s really fun to learn match by match,” she said. 

“A (fast start) is really important on grass, because of how fast it feels the matches go.

“But, honestly, I don’t really think about it; I just try to play my game, and thankfully, I did get a really good start.”

Osaka’s success was her best ever on grass and she celebrated by ringing her toddler daughter. “’’m going to call my daughter later, it always brightens my day to talk to her.”

Osaka’s previous grass quarter-final appearances all came at the 250 or Challenger level or lower dating back a dozen years.

After rushing from a Saturday finals loss in Germany to a Sunday training day at Wimbledon, Iga Swiatek is feeling the pressure of a packed-out tennis calendar.

The five-time Grand Slam champion whose Wimbledon best was a quarter-final two years ago has called again for a rationalising of WTA duties, with players constantly moving from one event to the next on a nearly nonstop basis.

“For me the scheduling is pretty intense. I think people would still watch tennis, maybe even more, if we played less tournaments,” the Pole said a day after losing the Bad Homburg final to Jessica Pegula.

“The quality, for example, would be better or we would be more consistent because of that (reduction of calendar pressure).”

Swiatek, who is ranked eighth after not winning a title since Roland Garros last season, added that the tennis grind is getting more and more demanding.

“This is for sure challenging. But tennis is a difficult sport overall.. every week you start kind of from the beginning.

“Every week can tell you if you’re a great player or you sucked this week, you know.

“I think the scheduling is too intense. There’s no point for us to play, like, over 20 tournaments in a year.

“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 (points) in the ranking.

But amid her cry for help is a saving grace: “You always have to have in the back of your mind that tennis is not your whole life. 

“You’ve got to give some perspective and also be proud of sometimes even when you don’t win, because only one person out of the whole tournament wins.”
