Serena Williams continued her march towards a sixth Wimbledon singles crown as she reached the quarter-finals with a straight sets victory over sister Venus on Centre Court.
The top seed won 6-4 6-3 in 70 minutes, to make it 25 straight victories in Grand Slam tournaments.
The 33-year-old was serving close to her best and, apart from being broken in the fourth game of the opening set, never looked in danger of dropping her service again.
Serena sent down 10 aces to just two from Venus, while also avoiding any double faults. In her final seven service games she conceded just eight points.
Venus, meanwhile, had to save five break points on her own serve otherwise the margin would have been wider.
In the end, Serena's ability to combine power with accuracy proved too much for the 35-year-old Venus whose most recent Grand Slam title came seven years ago.
The match was a complete contrast to Serena's three-set victory over Heather Watson on Friday when the British player came within a couple of points of beating the world No 1.
And if the younger sibling can win three more matches this week, she will hold all four Grand Slam titles for the second time in her career.
She previously held the quartet of titles in 2003 and, if she were to win here for a sixth time, it would be her 21st Grand Slam success.
Possibly the only milestone remaining for Serena to achieve would be to win all four Slam events in the same year – a feat last completed by Steffi Graf in 1988.
In Wednesday's quarter-finals, she will face two-time Australian Open champion Victoria Azarenka (23) who eased past 18-year-old Swiss star Belinda Bencic (No 30 seed) 6-2 6-3.
Serena is the third American to reach the last eight at Wimbledon this year, following early victories by Madison Keys and Coco Vandeweghe.
Garbine Muguruza will make her quarter-final debut at Wimbledon against 15th-seeded Timea Bacsinszky, winner over Romanian Monica Niculescu 1-6 7-5 6-2, after seeing off fifth seed Caroline Wozniacki of Denmark 6-4 6-4.
Wozniacki is a former top-ranked player but has never gotten past the fourth round at the All England Club.
Muguruza will next face on Tuesday.
Agnieszka Radwanska, 2012 Wimbledon runner-up, beat former top-ranked player Jelena Jankovic of Serbia 7-5 6-4.
Fourth-seeded Maria Sharapova overcame Zarina Diyas of Kazakhstan 6-4 6-4 to set up a clash with unseeded Vandeweghe 11 years after the Russian won her first major title at Wimbledon in 2004.
