Kostyuk claims biggest title of career with victory over Andreeva in Madrid

• Ukrainian wins 6-3, 7-5 at the Caja Mágica

• Title means Kostyuk will break into top 15 for first time

Marta Kostyuk took an enormous step towards fulfilling her potential as the Ukrainian closed out an incredible week by winning the biggest title of her career at the Madrid Open, defeating Mirra Andreeva of Russia 6-3, 7-5.

Although Kostyuk’s run through a WTA 1000 draw was unexpected, this title did not come out of nowhere. Kostyuk won her second career WTA event in Rouen just before Madrid, and has now put together an 11-match winning streak.
