In a classic contest between the contrasting styles of attack and defence, the 28-year-old Collins came out on top by firing rocket groundstrokes from both her forehand and backhand in front of an appreciative crowd in the day's final match at the Arthur Ashe Stadium. Collins, who finished runner-up at the Australian Open this year, will next face sixth seed Aryna Sabalenka in a battle of hardhitters for a spot in the quarter-finals. "This is one of my favourite slams. But didn't have my best results at this specific one," Collins, who beat two-time former champion Naomi Osaka in her opening round, said. "To be able to kind of have my best results that I've had here has been great. Obviously want to try to take it to the next level and do the best I can. With the way I'm playing, I've just got to take it one match at a time."
