Snapshot of day 11 at the Australian Open

SNAPSHOT FROM DAY 11 OF THE AUSTRALIAN OPEN AT MELBOURNE PARK:

PLAYER OF THE DAY: Madison Keys - a decade after making the last four as a teenage prodigy, the American downed Elina Svitolina in three hard-fought sets to reach the Open semi-finals for a third time.

STAT OF THE DAY: World No.2 Iga Swiatek has conceded a grand total of seven games in her past four matches en route to the final four.

PIC OF THE DAY:

QUOTE OF THE DAY: "I love you, thank you for supporting me. But when are you going to sleep?" Djokovic said after his 1am finish.

THE MOMENT: Fresh off her return to the tour after a one-month doping ban, Swiatek was embroiled in a double-bounce controversy during her quarter-final win over Emma Navarro.

TOURNAMENT SUMMARY: Swiatek will play Madison Keys in Thursday night's second women's semi-final after two-time defending champion Aryna Sabalenka squares off with born-again Paula Badosa. Gold Coast teenager Emerson Jones has lived up to her top seeding to make the junior girls' quarter-finals and could face Australian wildcard Tahlia Kokkinis in the last four.
