Semifinal line-up was set up at the Porsche Tennis Grand Prix on Friday, as Petra Kvitova, Naomi Osaka, Kiki Bertens and Anett Kontaveit won their quarterfinal matches.
The first player to make the final four was Petra Kvitova, seeded third, who rallied to beat seventh seed Anastasija Sevastova 2-6 6-2 6-3. What followed on Centre Court was an amazing battle between top seed Naomi Osaka and Donna Vekic, in which the world No.1 kept her composure and won 6-3 4-6 7-6(4) even though her opponent was serving for the match twice.
