One of the biggest wins of my career. BELLIS

Soon after the match, Cici commented

“I think this is definitely one of the biggest wins of my career. I’m just really happy with how I played, and really excited I was able to get through it.

I don’t think Kvitova played her best tennis, but on my side, I feel like just I played a real unbelievable match, from my standings.”
