Andy Murray's rapid progress to the Wimbledon quarter finals suffered a rain delay while the Centre Court roof was put back in place.
The defending champion had already begun his demolition job on South African Kevin Anderson, seeded 20, winning the first set 6-4 and broke twice to go 3-0 up in the second.
After the rain, Anderson threatened to make a comeback but Murray re-established his dominance before taking the set 6-3.
Anderson was serving at 132mph but Murray was largely untroubled, solid on his own serve and actually outscoring his opponent in aces.
Meanwhile grass court specialist Feliciano Lopez beat big serving John Isner 6-7, 7-6, 7-6, 7-5.
And Sabine Lisicki, leading Ana Ivanovic by a set on Saturday evening, completed a three set victory 6-4, 3-6, 6-1 and now faces Kazackstan's Yaroslava Shvedova in the fourth round.
Earlier, former world number one Caroline Wozniacki became the latest women's seed to taste defeat, going down 6-2, 7-5 to Barbora Zahlavova Strycova.
