MELBOURNE, Australia — It's men's semifinal day at the Australian Open and we'll soon learn who will be facing off for the title on Sunday evening. In the first semifinal, world No. 1 Carlos Alcaraz takes on third-seed Alexander Zverev. Later, reigning champion Jannik Sinner battles 10-time winner at Melbourne Park, Novak Djokovic.

Earlier on Day 13, Australian duo Olivia Gadecki and John Peers defended their Australian Open mixed doubles title, coming from a set down to beat Kristina Mladenovic and Manuel Guinard.

Yesterday, top-ranked Aryna Sabalenka booked her place in the women's final for the fourth consecutive year. She will square off with fifth-seed Elena Rybakina for the silverware, in a repeat of the 2023 Australian Open final.

The debate surrounding player privacy also continues to rage on Down Under in the wake of world No. 3 Coco Gauff's racket-smashing fit in the aftermath of her quarterfinal loss to Elina Svitolina. Tennis Australia CEO Craig Tiley has since weighed in on the debate.
