Serena Williams produced a stunning performance to beat second seed Simona Halep and set up an Australian Open semi-final with Naomi Osaka.

The thirty nine year old American, bidding for a record-equalling twenty fourth Grand Slam title, won 6-3 6-3 against the Romanian.

Earlier on Tuesday, Osaka cruised past Hsieh Su-wei in just sixty six minutes to reach the last four.

The Japanese third seed, who won the second of her three Grand Slam titles at Melbourne Park in 2019, beat the Taiwanese 6-2 6-2.

Now Osaka will face 10th seed Williams – a seven-time champion in Melbourne – on Thursday for a place in Saturday’s final.

It will the first meeting between the pair since their infamous 2018 US Open final.
