WORLD No 1 Angelique Kerber has survived a massive Wimbledon scare from American Shelby Rogers before scrambling into the fourth round.
The German was taken to the brink before posting a 4-6 7-6 (7-2) 6-4 victory.
Ranked 70th, Rogers scorched 48 winners to Kerber's 25, but committed 47 unforced errors to the left-hander's 14.
Rogers enjoys a formidable reputation as a giantkiller, having toppled Simona Halep at January's Australian Open and Petra Kvitova at last year's French.
And when Kerber trailed 2-4 (0-30) in the second set, it appeared the hard-hitting American was primed to add another big scalp to her collection.
Kerber settled and systematically worked her way out of danger.
French Open winner Garbine Muguruza has continued a menacing charge into Wimbledon's second week.
The Spanish former world No 2 overwhelmed Romanian Sorana Cirstea 6-2 6-2 in just 70 minutes to reach the fourth round.
Yet to drop a set in three matches, the 2015 Wimbledon finalist will play world No 1 and 2016 runner-up Angelique Kerber on Monday if the German rolls Shelby Rogers.
Russian veteran Svetlana Kuznetsova was another to take advantage of perfect conditions to progress.
The dual grand slam champion ousted Slovenian Polona Hercog 6-4 6-0.
Kuznetsova will next play Poland's Agnieszka Radwanska after the ninth seed beat Swiss Timea Bacsinszky 3-6 6-4 6-1.
Regarded as a bolter by many, Slovakia's Magadela Rybarikova again underlined impressive grasscourt credentials with a 6-2 6-1 destrution of Lesia Tsurenko, of the Ukraine.
Rybarikova has won 16 of 17 matches on grass this season after recovering from wrist and knee surgery.
Ranked No 87 in the world, Rybarikova eliminated world No 3 Karolina Pliskova in the second round.
She will next face Croat qualifier Petra Martic, who downed Zarina Diyas, of Kazakhstan, 7-6 (8-6) 6-1.
Coached by Pat Cash, Coco Vandeweghe raced past US compatriot Alison Riske 6-2 6-4 with 23 winners to five.
