Stefanos Tsitsipas battled into the Australian Open's last eight on Sunday but women's top seed Iga Swiatek and a tearful Coco Gauff became the latest big-name victims.
Swiatek's defeat to Elena Rybakina made it the first Grand Slam since the Open era began in 1968 to lose the top two seeds in both the men's and women's draws before the quarter-finals.
