Number five seed Elina Svitolina of Ukraine went through to the third round of the Australian Open on Thursday after proving too good for 16-year-old American prospect Coco Gauff. The 2019 Wimbledon semi-finalist completed a 6-4, 6-3 victory over the youngest player in the women's draw in an hour and 17 minutes. Svitolina will play No.26 seed Yulia Putintseva of Kazakhstan next.
