STUTTGART, Germany - Teenage sensation Marta Kostyuk took another major scalp on Tuesday as she qualified for the main draw of the event by defeating Alizé Cornet, 4-6, 6-2, 6-3.
The 15-year-old went down in the opening set but battled back impressively to oust the WTA World No.35 to score one of the biggest wins of her career.
The teenager proved her victory over then-WTA World No.27 Peng Shuai in the Australian open was no fluke by storming back to comfortably take sets two and three to reach the tournament proper.
Kostyuk, ranked 158 in the world, competed her win in almost exactly two hours, and was particularly strong on the return of serve, winning 47% of the points off her opponents' first delivery and 67% of break points she fashioned.
It is the second time she has qualified for the main draw of a WTA competition this year, having previously reached the last 32 of the Australian Open, where she was beaten by Elina Svitolina.
