Spain's Rafael Nadal on Friday advanced into his sixth Australian Open final and is now one win away from becoming the first men's player in history to take home 21 grand slam titles.
The sixth seed beat Italian Matteo Berrettini (7) in a tight 6-3, 6-2, 3-6, 6-3 in two hours, 55 minutes under a closed roof due to a storm.
"I had to suffer and I had to fight but to be in the final again means a lot," Nadal, 35, said after the match.
He is tied at 20 grand slam wins with Serbia's Novak Djokovic, who was expelled from Australia before he could compete, and Switzerland's Roger Federer, who did not participate due to injury.
The Spaniard will face the winner of Friday's other match between Russia's Daniil Medvedev (2) and Greece's Stefanos Tsitsipas (4).
