Kasatkina got off lightly with “only” 13 double faults and fought his way into the round of the last four.
There she faces the Spaniard Paula Badosa. Veronika Kudermetova and Shelby Rogers meet in the second semi-final.
For Sabalenka, however, a sad record continues. The number six in the world made numerous double faults this season.
In her 35 matches so far this calendar year, the 24-year-old has caused a total of 276 double faults – making her the double fault queen in women’s tennis.
