Mirra Andreeva was the last person on Centre Court to realize she beat Emma Navarro, a result that made her the youngest woman in 18 years to reach the Wimbledon quarterfinals.

It has been a fortnight filled with surprises, and Navarro is one of four top-10 seeds left in the women’s bracket. The others are No. 1 Aryna Sabalenka, who won her third-round match Friday against Emma Raducanu, Andreeva and No. 8 Iga Swiatek, a 6-2, 6-3 winner against Danielle Collins on Saturday.
