CINCINNATI–Iga Swiatek moved into the semi-finals of the Cincinnati Open as Elena Rybakina was forced to retire with a heel injury less than half an hour into their clash Thursday.

Rybakina’s withdrawal raised concerns over the fitness of the world number two Kazakh just 10 days before the start of the US Open.

Trailing 4-1 in the opening set of Thursday’s Cincinnati quarter-final, Rybakina suddenly pulled up short at 40-all, heading to her bench and consulting with the trainer.

She went back out and played one more point before quitting.

“I was feeling anxious watching the whole situation,” said her opponent Swiatek. “I hope she will be fine. Health is always the priority.”

“This is an important tournament, but the US Open is the US Open. I hope she is ready for that,” she said, referring to the major which begins in New York on August 30.

“It was a shame she was injured, we were having a good match.”

Had two-time Grand Slam winner Rybakina reached the Cincinnati Open final she would have risen to number one in the world for the first time in her career, following incumbent Aryna Sabalenka’s shock exit to 20-year-old Sara Bejlek.

Defending Cincinnati champion Swiatek said she had “gained a lot of confidence in the last weeks,” which have also included her victory over Rybakina in the final of this month’s Toronto event.

“I feel great, ready to play my game… I’m happy to be playing the tennis that I am.”
