Marta Kostyuk into third round of the Australian open 2018

MELBOURNE, Australia
15-year-old Marta Kostyuk needed just two sets against local wildcard Olivia Rogowska to reach the third round in her Australian Open debut.

Last year’s Australian Open Junior champion, Kostyuk made it 11 victories in a row in Melbourne, backing up her first-round upset of No.25 seed Peng Shuai to defeat the Aussie favorite 6-3, 7-5 on Margaret Court Arena.
