Kirsten flipkens beat the top seed of the WTA 500 from Abu Dhabi. The Belgian was 7-5 up and was fighting break down in the second before Sofia Kenin.
At the end of the ninth game, the Belgian went to look for a ball in the back and slipped with an advertising sign. He sprained his ankle, lost the point (5-4 for Kenin) and had to leave the game.
In this way, the American advanced to the round of 16 where she will face Putintseva.
