The defending champion and world No 1, Iga Swiatek, showcased all her experience to book a semi-final place at the Porsche Tennis Grand Prix in Stuttgart. Swiatek fought back from a set down against Karolina Pliskova to claim a 4-6, 6-1, 6-2 victory. She will now face the Tunisian Ons Jabeur, who dropped only three games in seeing off Beatriz Haddad Maia 6-3, 6-0.

Swiatek is one win away from reaching the final in her first tournament for over a month after suffering a rib injury.
