Wimbledon 2018 progressed into the third day as Roger Federer as well as Serena and Venus Williams progressed into the third round, on the same day that top seeds in the women's draw continued to tumble.
Top seed Federer admitted before the match that he can still get nervous walking out on to Centre Court but he was at his free-flowing best against Lajovic who was little more than a prop in Federer's magic show.
Five-time Wimbledon champion Venus Williams once again dropped the opening set, and once again dominated the rest of the way to win.
The second seed complained about the nuisance the ants were causing and perhaps suffered as a result because she lost to Russia's Ekaterina Makarova 4-6, 6-1, 5-7.
Federer has been in imperious mood in pursuit of his ninth Wimbledon crown, while Williams is rounding into form just as the seven-time champion's rivals have collapsed all around her. He converted 5 break points and won 93% of his first service points.
Those who have spent enough time in the Wimbledon press conference room will remember when Roger Federer used to speak of his ambition to keep playing until the London Olympics.
