Marin Cilic is in exclusive company at the Australian Open.

With his 3 set semifinal win over 49th‑ranked Kyle Edmund, Cilic became only the second man from outside the "Big Four" to reach the final at season‑opening major in a decade.

Roger Federer, Rafael Nadal, Novak Djokovic and Andy Murray have dominated the men's finals since 2009, with only 2014 champion Stan Wawrinka breaking the quartet's court occupation in the championship match.

The 29‑year‑old Cilic, the first Croatian to make the final at Melbourne Park, could face the founding member of the "Big Four" in the final on Sunday.

That's if defending champion Federer can get past Hyeon Chung today.

Women’s World number one Simona Halep quelled a tenacious Angelique Kerber fightback and saved two match points to reach her first Australian Open final.

The Romanian, Halep will now face Denmark's Caroline Wozniacki in the first Australian Open final between two players still chasing one of the four majors since 1980 with the number one ranking also on the line.
