Angelique Kerber will surrender her status as world No. 1 after Garbine Muguruza knocked her out of Wimbledon on Monday, 4-6, 6-4, 6-4. Elsewhere, Johanna Konta progressed to the quarter-finals after beating Caroline Garcia 7-6(3), 4-6, 6-4.
Konta entered the competition coming off a spine injury she suffered at the Aegon International last month, but she moved into the last eight with a hard-fought victory over No. 21 seed Garcia.
Meanwhile, French Open champion Jelena Ostapenko beat fourth seed Elina Svitolina 6-3, 7-6(6), and seventh seed Svetlana Kuznetsova saw off ninth seed Agnieszka Radwanska 6-2, 6-4.
The full results can be found at Wimbledon's official website.
Britain's Konta continued to shrug off her spinal issues with an impressive triumph over French hopeful Garcia, whose forehand almost saw her pinch the result following a fight back to parity after the second set.
In qualifying for the quarters, Konta also broke a British duck stretching back more than two decades, becoming the first British woman to reach a Wimbledon quarter-final since Jo Durie did so in 1984, per BBC Sport.
Only fine margins separated the two in what always seemed destined to be a close encounter, winning on 75 per cent of her first-service points, compared to Garcia's only slightly inferior—but no less telling—68 per cent, per the IBM Slamtracker.
Both players were fighting to stay in the match as Konta led 5-4 entering the final game on Garcia's serve.
Muguruza entered her match having won her last four contests with Kerber, but it looked as though the German might avoid defeat on this occasion when she edged out the Spaniard in a tight first set.
Record's Jose Morgado noted how much more cleanly she played than Muguruza, pointing out Muguruza's 21 errors to Kerber's three. However, she missed a gilt-edged chance to break in the second, and the 14th seed made her pay, taking them to a decider.
After just one break apiece in the first two sets, the thrilling third set saw five between the pair, with Muguruza sealing her final break and the match when Kerber netted a backhand.
The New York Times' Ben Rothenberg detailed the rankings situation following Kerber's defeat, noting Kerber was the WTA's top player for 34 weeks, which is longer than any stretch in the careers of Venus Williams, Maria Sharapova and others.
Kuznetsova eased through the first set of her match with Radwanska without breaking a sweat as she quickly set about breaking the Pole twice. The ninth seed was able to make the second set slightly more competitive and managed to save six break points, but the Russian's superiority was clear as she saw it out in straight sets.
Ostapenko's attacking style helped her break Svitolina on no less than three occasions in their first set, and she did the same in the second. However, the Ukrainian showed remarkable resilience to not only force a tiebreaker but also save seven match points during the course of the contest before eventually succumbing.
