Serena Williams moved to the Wimbledon quarter-finals by beating her sister Venus in their first showdown at the grass-court tennis tournament in six years.
Serena won 6-4, 6-3 at the All England Club to reach her first Wimbledon quarter-final since her last title here in 2012.
"It's never easy to play someone you love and care about," she said in a televised interview after the match. "I'm 33, she just turned 35. I don't know how many more moments like this we'll have. We're at Wimbledon. I remember when I was eight years old, we dreamed of this moment."
Seven-time Wimbledon champion Roger Federer moved to the last eight for the 13th time, defeating Spain's Roberto Bautista Agut 6-2, 6-2, 6-3. The Swiss, who last won the title at the All England Club in 2012, will play Gilles Simon, who upset No. 6 Tomas Berdych. Federer won the last five meetings with the Frenchman.
Defending champion Novak Djokovic of Serbia came back from two sets down to even his match against South Africa's Kevin Anderson. They will continue today after play was suspended due to darkness just after 9pm.
Andy Murray, the 2013 winner from Britain, dismantled the serve of 6-foot-11 Ivo Karlovic, 7-6 (9-7), 6-4, 5-7, 6-4. The Croat hit 29 aces, taking his tally for the tournament to 165.
France's Richard Gasquet defeated Australian Nick Kyrgios in four sets, 7-5, 6-1, 6-7 (7-9), 7-6 (8-6), in a match full of outbursts from both sides.
The 20-year-old Kyrgios, who stunned two-time champion Rafael Nadal in the fourth round last year, refused to hit the ball for an entire game after receiving a code violation from umpire James Keothavong for swearing.
He also argued with Keothavong for taking too long to change his socks. Gasquet smashed his racket on the ground and then on his chair after he failed to take two match points in the third set, which Kyrgios ended up winning.
"He was a little bit angry a little bit frustrated, I saw that," said Gasquet, who who faces French Open winner Stan Wawrinka next.
