Poland will have a woman in the semi-final of the Australian Open after Magda Linette emerged victorious 6-3 7-5 in Wednesday's quarter-final against Karolina Pliskova.

World number one Iga Swiatek was expected to be flying the flag for Poland deep into the tournament, but after her surprising exit it is now the 30-year-old Linette who will try to step up and go all the way.

Having never advanced past the third round at any of her previous 29 grand slam appearances, Linette has now hit a remarkable run of form that includes consecutive wins over world number 19 Anett Kontaveit, world number 18 Ekaterina Alexandrova, and world number four Caroline Garcia.

Against Pliskova – a former world number one – Linette capitalised on some sloppy play as her Czech opponent committed an uncharacteristic 36 unforced errors with only 18 winners.

Pliskova also committed seven double-faults, leading to a meagre 58 per cent success rate (34-of-59) from her service points, while Linette converted at a 70 per cent clip (45-of-64).

Speaking on the court immediately after her triumph, Linette said: "I will never forget this. This is the first time ever I'm breaking through some really difficult things for me. This will stay with me for life, so I'm really grateful and super happy for the support."

Linette will face the winner between Aryna Sabalenka and Donna Vekic in the semi-final, while Elena Rybakina and Victoria Azarenka will battle it out for the other spot in the decider.
