Eighteen-time grand slam champion, Serena Williams, and her older sister, Venus, once again made the fourth round of a grand slam. A first appearance at this stage for Venus in the singles since 2011, the year she was diagnosed with Sjögren's syndrome. On the brink of defeat in the previous round, the 34 year old showed resilience in a comeback over the big hitting Italian, Camila Giorgi. Trailing a set and a point from double-break disadvantage, Williams fought off multiple break points to take the second set tiebreak before cruising in the decider to a 4-6 7-6(3) 6-1 victory. The nearly 2.5 hour encounter was physical and emotional for the former World No. 1 trying to make her way back to the top echelon of tennis. "It's definitely been a lot of work and a lot of learning and a lot of perseverance. It will continue to be that for me. Just have to come to terms with it", said Williams. With the win, she is projected to rise to No. 12 in the WTA ranking and is slated to play No. 6 Agnieszka Radwanska who defeated American Varvara Lepchenko in straight sets.
