In-form Kostyuk sets up French Open semi-final with ruthless Andreeva

• Emotional Kostyuk beats Ukrainian compatriot Svitolina

• Mirra Andreeva eases past Sorana Cirstea 6-0, 6-3

Marta Kostyuk was her own toughest rival for so long during the early stages of her career. As she tried to navigate the pressure that accompanied her status as a teenage prodigy, she often struggled to think clearly on the court without her emotion, fears and desperation to succeed torpedoing her form.

The path towards unlocking her potential has been tough, requiring the Ukrainian to be honest with herself and encounter the right people to help take her forward. That work continues to pay off. Kostyuk made another significant breakthrough by ending the Ukraine derby as the victor, holding her nerve to defeat Elina Svitolina 6-3, 2-6, 6-2 and reach the semi-final of a grand slam for the first time in her career.
