Andy Murray reached the Wimbledon last 32 Thursday while Serena Williams' path to a record-equalling 22nd Grand Slam was eased by a shock defeat for world number two Garbine Muguruza.
Murray, the world number two and champion in 2013, crushed Taiwan's Lu Yen-Hsun 6-3, 6-2, 6-1, hitting 31 winners and serving six aces.
He will face Australian world number 67 John Millman for a place in the last 16.
"There were a lot of close games in the first set, but once I managed to hang on there I settled down," Murray said.
But it was Serbia's Viktor Troicki who stole the show - making a case for the greatest Wimbledon rant of modern times as he slipped to a five-set defeat to Spain's Albert Ramos Vinolas.
Infuriated that umpire Damiano Torella had over-ruled a Vinolas serve which was called out to declare it an ace, Troicki unleashed a tirade of abuse at the Italian official.
"You're the worst umpire in the world, you're so bad," screamed Troicki as he went match point down and he continued in the same vein when the match concluded. "You're horrible, you know what you did. You are an idiot."
