Second seed Rafael Nadal ended Greek youngster Stefanos Tsitsipas‘ captivating run to reach his fifth Australian Open final.
Nadal, 32, was in devastating form as he beat the 20-year-old 14th seed 6-2 6-4 6-0 in one hour and 46 minutes.
The Spaniard cracked 28 winners, breaking Tsitsipas’ serve six times and only facing one break point himself.
He will play either top seed Novak Djokovic or France’s Lucas Pouille – who meet on Friday – in Sunday’s final.
“It was a great match, it has been a great tournament and I have played very well every day,” Nadal said.
“Hopefully I can play better than that.”
Nadal, who won at Melbourne Park in 2009, is one more win away from winning all four Grand Slams at least twice – a feat which no other man has achieved in the Open era.
Serbia’s Djokovic is also chasing a slice of history as he bids for a record seventh men’s singles title, although he must first beat Grand Slam semi-final debutant Pouille.
You can follow the match on the BBC Sport website and BBC Radio 5 live sports extra from 08:30 GMT.
Osaka Holds Off Pliskova To Make Final
US Open champion Naomi Osaka reached back-to-back Grand Slam finals with a hard-fought win over Czech seventh seed Karolina Pliskova at the Australian Open.
The Japanese fourth seed won 6-2 4-6 6-4 and will face Petra Kvitova, another Czech, in Saturday’s showpiece.
Osaka, 21, hit 15 aces and 56 winners in a confident display.
The semi-final was played under the Rod Laver Arena roof as temperatures touched 40C in Melbourne.
Osaka hit another forehand winner to give herself a match point at 40-30, shouting “come on” as she looked up to the sky and tried to compose herself, then hit what she thought was an 111mph ace down the middle.
After it was called out, Osaka challenged and clasped her hands together in hope as she watched the replay – and was left celebrating when Hawkeye showed the ball had clipped the line.
Asked about her feelings when Pliskova won the second set, Osaka said: “I kind of expected it a little because I’ve played her so many times and she has beaten me more than I’ve beaten her. I told myself to regroup and I managed to win.
“It’s just experience playing matches like this. I was so scared serving second serves, I was like ‘oh, my god, please’ and somehow I made it so I guess that’s experience.”
The final will see Osaka and 28-year-old Kvitova, who has reached her first Grand Slam final since being stabbed in December 2016, battling for the world number one ranking.
Defeat ended 26-year-old Pliskova’s hopes of reaching her second Grand Slam final and setting up a first all-Czech final against her Fed Cup team-mate.
