Naomi Osaka has never lost a Grand Slam after making the quarterfinals, and if all goes to plan at the Australian Open, she will be savoring a fourth major triumph before her 24th birthday.
The Japanese third seed reached the semifinals with a clinical 6-2, 6-2 win over Hsieh Su-wei on Tuesday, two years after suffering a big scare in an emotional rollercoaster of a match against the Taiwanese maverick at the 2019 tournament.
Osaka's opponent in the semifinal will be Serena Williams, who also won on Tuesday.
