Cilic joins an elite group

Marin Cilic is in exclusive company at the Australian Open.

With his 6-2 7-6 (4) 6-2 semifinal win over 49th-ranked Kyle Edmund, Cilic became only the second man in a decade from outside the ‘‘Big Four’’ to reach the final of the season-opening tennis major.

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 is if defending champion Federer got past Hyeon Chung in the semifinals on Friday.

Cilic lost to Federer in last year’s Wimbledon final, where he was injured and struggling at the end. This time, he has held off No 10 Pablo Carreno Busta and topranked Rafael Nadal and thinks, with two days to rest before the final, he’ll be in better shape.

‘‘I’m feeling really, really good physically,’’ he said. ‘‘I played a great tournament so far with my level of tennis.

‘‘I improved it comparing to end of the last year. I’m playing much, much more aggressive - feeling really excited about the final, too.’’

It’ll be a third major final for Cilic, who beat Federer in the semifinals at the 2014 US Open before going on to win his breakthrough Grand Slam title.

He reached the semifinals in Melbourne in 2010, then waited 16 more majors to surpass that level by reaching that US Open final.

The long wait didn’t bother him. Besides, his 10 attempts to reach the Australian final equalled an Open era record held by 1980 runner-up Kim Wawrick.

Cilic was under pressure early against Edmund and had to fend off break points in the opening game.

He held and quickly got on top in the first set and, after maintaining his composure in a nervy second-set tiebreaker, quickly established a break in the third set.

‘‘I think in that second set, I was just a little up and down with my game. I wasn’t getting enough returns back to put pressure on him in his service games,’’ Cilic said.

‘‘I noticed that in the third game in third set, when I broke him, he just let a couple balls go past him ... I was seeing with this movement he was a little bit restricted so I just tried to move the ball around.’’
