Simona Halep (#5) of Romania looks like she's on track to get the semi-final slot of her side of the draw as she tames Dutch wunderkind Kiki Bertens in the 3rd round 64 63.
In the first round, she took care of Anna Karolina Schmiedlova (#40) of Slovakia 64 61. Then won over Italian grand slam champion Francesca Schiavone (#111) in the 2nd round 61 61.
Today, she defeated Madison Keys (#9), 67(5) 64 63 in their fourth round match. She is now set to meet Angelique Kerber (#3) in their quarterfinal match.
She has a winning head-to-head record with Kerber, that's why she's now the pick to take the semi-final slot on her side of the draw - a slot which was first predicted on Czech Karolina Pliskova.
