Serena Williams produced a stunning performance to beat second-seed Simona Halep and set up an Australian Open women's singles semi-final with Naomi Osaka. The 39-year-old American, bidding for a record-equalling 24th Grand Slam title, won 6-3, 6-3 against the Romanian.
 
Earlier today, Osaka cruised past Hsieh Su-wei in just 66 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.
 
In Men's Singles quarterfinals, defending champion Novak Djokovic beat German sixth-seed Alexander Zverev 6-7, 6-2, 6-4, 7-6 and reached the semi-finals.

The Serb will face Russian qualifier Aslan Karatsev, who beat an injured Grigor Dimitrov. Karatsev, ranked 114th in the world, is the first man in the Open era to reach the last four on his Grand Slam debut.
