Aryna Sabalenka said her mentality in Melbourne was ¡°trophy or nothing¡± after muscling past American teenager Iva Jovic into the Australian Open semifinals on Tuesday to put a third title within sight.

The relentless top seed powered home 6-3, 6-0 in blazing heat to set up a clash with either third seed Coco Gauff or 12th seed Elina Svitolina.

It booked her a 14th Grand Slam semifinal and fourth in a row at the season-opening major.
