No.1 seed Alizé Cornet and former World No.5 Eugenie Bouchard are both seeking to make their first semifinal since January 2017. Bouchard's most recent run to the final four was at Sydney that month; Cornet's most recent last four showing was the week before in Brisbane.
Mandy Minella, playing her first WTA quarterfinal since returning from maternity leave in February, is 0-2 against her opponent today, Sara Sorribes Tormo. The Spaniard has won both of their previous meetings in three sets: 3-6, 6-1, 6-3 in the qualifying of Marrakech in 2015, and 6-4, 6-7(5), 6-3 in the first round of the Contrexéville ITF $100,000 event last week.
Qualifier Veronika Kudermetova is playing the third WTA main draw of her career. So far, the 21-year-old has improved by one round every time, having scored a second-round showing in Stuttgart and a quarterfinal in 's-Hertogenbosch.
Alizé Cornet will face either No.5 seed Samantha Stosur or wildcard Patty Schnyder in the quarterfinals. The Frenchwoman trails Stosur 2-5, all on hard courts, and has not beaten the Australian in nearly a decade, since victory in the first round of Beijing in 2009. Since then, Stosur has reeled off four straight wins, with their most recent encounter in Beijing 2014 going to the former US Open champion 6-4, 6-2. Cornet has split two meetings with Schnyder, with the Swiss player winning 6-2, 6-1 on the clay of Prague in 2010 and Cornet gaining revenge a year later in Indian Wells.
