In the last match of the day, 18-year-old Whitney Osuigwe continued her stunning turnaround in form with a three-set win over Romanian Mihaela Buzarnescu.
The American teen had lost 11 of her final 12 matches in 2020, having not tasted not tasted victory since February. And she looked headed for another defeat when she trailed Buzarnescu 6-2 5-2.
Yet buoyed by a new mentality, she rebounded to record an inspiring 2-6 7-6(1) 6-2 triumph.
"I really tried to make that my identity, never giving up. It shows in tennis it's never over until it's actually over, so I kept that in the back of mind the entire time," Osuigwe said.
"Last year was tough, and I think at a point in time I started not enjoying tennis. So a big part of coming into this year was just finding my happiness with tennis again, just leaving 2020 behind me and starting fresh.
"During the pre-season I was on the track every single day, practising twice a day, so I worked really hard to get to where I am right now.
