Aryna Sabalenka won the Australian Open in 2023 and 2024 but lost last year's final to Madison Keys

Aryna Sabalenka says her mentality is "trophy or nothing" as she maintained her pursuit of a third Australian Open title in four years with a dominant quarter-final victory over teenager Iva Jovic.

World number one Sabalenka overpowered rising American star Jovic 6-3 6-0 and awaits either third seed Coco Gauff or Ukraine's Elina Svitolina in the semi-finals.

The 27-year-old Belarusian, a four-time major singles champion, has made the semi-final stage at 14 of the last 17 majors she has contested.

Sabalenka is only the third women's player to reach eight consecutive singles semi-finals at Grand Slams in the past 38 years, after Lindsay Davenport and Martina Hingis.
