Down 5-4 in the first set and with her opponent stepping to the line to serve, Serena Williams was on the brink of going a set down at Wimbledon in the fourth round.
Then she won nine games in a row.
The world No. 1 and defending champion breezed through the latter half of her match against 31-year-old Svetlana Kuznetsova, besting the Russian who had beaten her earlier this year in Miami with a 7-5, 6-0 effort.
What’s next for Serena? Another Russian: No. 21 seed Anastasia Pavlyuchenkova, who beat American CoCo Vandeweghe 6-3, 6-3 earlier in the day.
There was no such Serena luck for another American in Madison Keys, who led No. 5 seed Simona Halep by a set only to fall in three, 6-7(5), 6-4, 6-3. Halep will meet Australian Open Angelique Kerber in the last eight. All four women’s quarterfinals will take place on Tuesday.
2014 Australian Open runner-up Dominika Cibulkova scored the upset of the day over No. 3 seed Agnieszka Radwanska in what was no doubt the match of the day. The hard-hitting Slovakian won 6-3, 5-7, 9-7 in an extended third set.
Yaroslava Shvedova beat Lucie Safarova in straight sets, as well.
Shvedova will face either Carla Suarez Navarro or Venus Williams, the two doing battle on No. 1 Court after a rain delay. Williams, leading in a first set tiebreak 4-2, won three of four points to go up by a set against the Spaniard who she had split six previous encounters with.
