Katie Volynets has scored the most significant win of her career with her upset defeat of world number nine Veronika Kudermetova, becoming the first American qualifier to reach the Australian Open women's singles third round in 30 years.
The 21-year-old — who is ranked 113 in the world — matched the feat of US great Lindsay Davenport, who made the third round in 1993, seven years before she claimed the women's singles championship.
