Agnieszka Radwanska ensured this year's Australian Open will crown a first-time female winner by snapping a seven-match losing streak against Victoria Azarenka.
Radwanska maintained her self-belief after gifting the second set to her nemesis, racing away to win the quarter-final 6-1 5-7 6-love against the two-time defending title-holder.
The Polish fifth seed's reward is a semi-final against fellow 24-year-old Dominika Cibulkova from Slovakia, continuing a rivalry that began back in the under-nines.
The other semi will pit number 4 seed Li Na against Canadian teen sensation Eugenie Bouchard.
