Halep battles past Tsurenko to set up Sabalenka semi

World number one Simona Halep has progressed to the semi-final of the Western & Southern Open in Cincinnati after a hard-fought victory over Lesia Tsurenko.

Haplep, playing her second match of the day, having earlier dismissed Ashleigh Barty 7-5 6-4 in their rain-delayed third-round clash, fought back from 4-1 down in the first set to rattle off 11 of the last 12 games, ousting Tsurenko 6-4 6-1.
