Konta scored one of the biggest wins of her career by beating third seed Pliskova, with celebrity fan Tom Hiddleston once again in her corner. She will face Elina Svitolina in the quarter-finals. Jamie Murray and Neal Skupski beat Denis Shapovalov and Rohan Bopanna in the men's doubles. Murray then teamed up with Bethanie Mattek-Sands to beat his old partner Bruno Soares and Nicole Melichar in the mixed.
