Iga Swiatek advanced to the semifinals of the Cincinnati Masters after Elena Rybakina withdrew with a heel injury during their quarterfinal match. The incident occurred less than an hour into the match, raising concerns about Rybakina’s fitness ahead of the US Open.

Rybakina, ranked world number two, was trailing 4-1 in the first set when she abruptly stopped playing. She consulted with her team and left the court, unable to continue. The sudden withdrawal has sparked discussions about her readiness for the upcoming Grand Slam.

Swiatek, the defending champion, will now face the winner of the other quarterfinal. The match was part of the WTA and ATP joint event in Cincinnati, Ohio.

The incident highlights the physical demands of professional tennis and the risks athletes face as they prepare for major tournaments.
