Unheralded Croatian Mirjana Lucic-Baroni has dumped No.3 seed Agnieszka Radwanska out of the Australian Open in straight sets.
Lucic-Baroni, ranked 79th in the world, attacked Radwanska’s serve from the outset, breaking her three times in the first set before going on to claim a 6-3 6-2 win on Margaret Court Arena.
Lucic-Baroni will play either Frenchwoman Alize Cornet or Maria Sakkari of Greece in the third round.
