Stefanos Tsitsipas struck a huge blow for the next generation by beating two-time defending champion Roger Federer in the fourth round of the Australian Open.
Tsitsipas next faces another first-time grand slam quarter-finalist in Roberto Bautista Agut while Rafael Nadal eased past Tomas Berdych and will take on Frances Tiafoe, who celebrated his 21st birthday with an emotional win over Grigor Dimitrov.
Ashleigh Barty became the first Australian woman to reach the last eight here for a decade by knocking out Maria Sharapova and next plays Petra Kvitova while American Danielle Collins stunned second seed Angelique Kerber for the loss of only two games.

Greece’s other leading player gives her reaction.
Frances and the king
“He commented ‘silencer’ (the name of the celebration) and he put a crown, two muscle emojis,” said Tiafoe. “I was like, ‘Clearly he knows who I am now. That’s just crazy’.”
Collins up for the fight
She said: “I love making it kind of a war. If somebody wants to get in my face on my unforced errors, I have no problem getting right back at them. I just love competition. Sometimes when people are all for me I’m like, ‘I hope somebody says something negative so I can prove them wrong’.”
Fallen seeds
Women: Angelique Kerber (2), Sloane Stephens (5), Maria Sharapova (30)
Men: Roger Federer (3), Marin Cilic (6), Grigor Dimitrov (20)
Who’s up next?
Following that, Novak Djokovic will look to avoid suffering the same fate as Federer when he takes on talented young Russian Daniil Medvedev.
Earlier, US Open champion Naomi Osaka faces Anastasija Sevastova while fourth seed Alexander Zverev will look to reach only his second slam quarter-final against in-form Milos Raonic.
