Alexander Zverev served up a huge shock at the Australian Open on Wednesday by stunning second seed Carlos Alcaraz to make the semi-finals after third seed Daniil Medvedev fought hard to avoid an upset at the hands of Hubert Hurkacz.

Ukrainian qualifier Dayana Yastremska and Chinese 12th seed Zheng Qinwen earlier progressed to the last four of a Grand Slam for the first time after contrasting victories from a wide open section of the women’s draw.
