American Sam Querrey defeated South African Kevin Anderson in five sets to set up a Wimbledon quarter-final against world number one Andy Murray on Wednesday.
Querrey, 28th in the world, defeated unseeded Anderson 5-7 7-6 (7-5) 6-3 6-7 (11-13) 6-3 in a match that lasted three hours seven minutes on court 18.
In 2016, Querrey beat Novak Djokovic at Wimbledon before losing to Milos Raonic in the quarter-finals.
Briton Murray has won seven of eight matches he has played against Querrey.
The 30-year-old Scot, who won Wimbledon in 2013 and 2016, moved into the quarter-finals for the 10th consecutive year with a 7-6 (7-1) 6-4 6-4 win over France’s Benoit Paire.
Also yesterday, former champion, Roger Federer had few problems in overcoming a sloppy Grigor Dimitrov 6-4 6-2 6-4 to secure his place in the last eight of Wimbledon.
The Swiss, chasing a record eighth title at the All England Club, had not dropped a set en route to the fourth-round meeting on Centre Court, but he can hardly have had an easier encounter than this one-sided affair.
Federer held a 5-0 record over Dimitrov before this clash – the pair’s first on grass – and the Bulgarian may be in no great hurry to face the world number five again after this dismal showing.
The 13th seed made 25 unforced errors and committed seven double faults as Federer was barely required to break sweat in wrapping up victory in just over an hour and a half.
In the women’s singles, top seed Angelique Kerber will lose her world number one ranking after being beaten by Spain’s Garbine Muguruza in the fourth round at Wimbledon.
Muguruza, the 14th seed and a runner-up at SW19 in 2015, won an enthralling match 4-6 6-4 6-4 in two hours and 20 minutes on court two.
The German, a finalist in 2016, had needed to reach Saturday’s final to have a chance of retaining her ranking.
Muguruza, 23, will play Svetlana Kuznetsova of Russia in the last eight.
Five-time Wimbledon singles champion Venus Williams also moved into the quarter-finals of the 2017 tournament with a routine win over Croatia’s Ana Konjuh.
Williams beat the 27th seed, who was born after the American made her Wimbledon debut in 1997, 6-3 6-2.
The 37-year-old, seeded 10th, will take on French Open champion Jelena Ostapenko in the last eight.
The 20-year-old from Latvia beat Ukrainian fourth seed Elina Svitolina 6-3 7-6 (8-6).
Svitolina saved seven match points in the second set, before Ostapenko, seeded 13th, finally won in a tie-break.
Elsewhere, Johanna Konta became the first British woman to reach the quarter-finals since 1984 with a hard-fought win over France’s Caroline Garcia.
Konta will play Simona Halep after the Romanian second seed’s 7-6 (7-3) 6-2 victory over Victoria Azarenka.
The 27-year-old Belarusian, playing only her second tournament after giving birth to son Leo in December, saved three match points before Halep triumphed.
If Halep beats Konta in the last eight, she will become world number one.
