Iga Swiatek came back from a set down against 17-year-old Mirra Andreeva to reach the Cincinnati Open semi-finals.
Women’s world No 1 Iga Swiatek survived a scare against 17-year-old future star Mirra Andreeva in their Cincinnati Open quarter-final, coming from a set down to win.
Swiatek was broken in her second service game of the match as she lost the opener 6-4, the Pole missing out on four break-back opportunities, including two when Andreeva was serving for the set.
Andreeva was, however, immediately broken to start the second set as Swiatek levelled the match and forced a decider.

With the contest deadlocked at 5-5 in the final set, Swiatek earned what appeared to be the crucial break.
But back came Andreeva, earning a break-point chance in the very next game that would have forced a deciding tie-break, only for Swiatek to hold firm and clinch a hard-fought victory three points later.
The five-time Grand Slam winner will next face soon-to-be world No 2 Aryna Sabalenka in the semi-finals following her comfortable 6-3 6-2 victory over Liudmila Samsonova.
Sabalenka is seeded third for the tournament, but is set to leapfrog Cincinnati defending champion Coco Gauff in the women’s rakings after her disappointing second-round exit.
