Sabine Lisicki of Germany reached the fourth round by beating 2008 French Open champion Ana Ivanovic 6-4, 3-6, 6-1 in a match that began two days earlier.
The second set was tied at one-all when the match was suspended because of darkness.
Wimbledon takes the middle Sunday off, which is why the 19th-seeded Lisicki and 11th-seeded Ivanovic did not resume until the day after.
Lisicki has made it to at least the fourth round on her last five appearances at the All England Club. She got to the quarter-finals in 2009 and 2012, the semifinals in 2011, and lost to Marion Bartoli in the 2013 final.
Lisicki next faces 65th-ranked Yaroslava Shvedova of Kazakhstan.
Murray routs Anderson
Defending champion Andy Murray moved into the Wimbledon quarter-finals for the seventh year in a row, beating 20th-seeded Kevin Anderson of South Africa 6-4, 6-3, 7-6 (6).
The match finished with the Centre Court roof shut after a brief rain delay early in the second set.
The third-seeded Murray has won all 12 sets he's played in the tournament this year, dropping 32 games. His All England Club winning streak is 17 matches, including the run to a gold medal at the 2012 London Olympics.
In 2013, Murray became the first British man in 77 years to win Wimbledon.
Anderson was trying to reach his first Grand Slam quarter-final, and would have been the first South African to get to Wimbledon's quarter-finals since Wayne Ferreira in 1994.
Djokovic beats Tsonga
The top-seeded Serbian beat Jo-Wilfried Tsonga for the 11th straight time to advance to the quarter-finals at the All England Club with a 6-3, 6-4, 7-6 (5) victory.
His left arm bothered him in the tiebreak when Tsonga hit the net cord to move up 3-2. The right-handed Djokovic, who uses his left hand on his two-handed backhand, did not chase the shot and grabbed the upper left arm he landed on in his prior match.
The pain did not last long and Djokovic finished strongly, hitting a cross-court backhand service return on the first match point. He received treatment on his arm after the match but said he felt fine.
