No. 1 Aryna Sabalenka reached the quarterfinals at her 11th consecutive Grand Slam tournament, defeating No. 24 Elise Mertens 6-4, 7-6 (4).

She will play Laura Siegemund, the 37-year-old German who followed up her elimination of Australian Open champ Madison Keys by beating lucky loser Solana Sierra 6-3, 6-2. When Siegemund's age was mentioned during an on-court interview, the crowd applauded, and she joked: “It's not that often you get such a compliment for being old.”

Also Saturday, Anastasia Pavlyuchenkova overcame a missed call late in the first set when the electronic system that replaced line judges at Wimbledon this year was shut off but ended up beating Sonay Kartal 7-6 (3), 6-4 to return to the grass-court major's quarterfinals for the first time in nine years.

Pavlyuchenkova's opponent Tuesday will be No. 13 Amanda Anisimova or No. 30 Linda Noskova.
