In many ways, it was a changing of guards, in many ways it was what the world had seen when Roger Federer was in his prime, Stefanos Tsitsipas all of 20, perhaps, knocked off Roger Federer in the Australian Open fourth round Sunday.
The young man, who has idolised Federer, handed him his first defeat in Melbourne for the first time in two years. Federer was ousted 6-7 (11-13), 7-6 (7/3), 7-5, 7-6 (7/5) at the Rod Laver Arena.
Remember, 2001, when Federer knocked off Pete Sampras at Wimbledon, Tsitsipas could well have done something similar today at the Rod Laver Arena.
"It's a bit of a desire. I'm in a phase where I want to have fun and I've missed not doing it. "I lost to a better player who was playing very well tonight. Hung in there, gave himself chances at some point, stayed calm. It's not always easy, especially for younger guys. Credit to him for taking care of that," he told reporters of the French Open.
"I don't feel it is necessary to have a big break again," he added.
"There's nothing really I can say to describe this," said the 20-year-old. "I'm the happiest man on earth right now," Tsitsipas said.
This is how Twitter took note of the stupendous performance by the young man, which was nothing short of historical.
