Reigning champion Jannik Sinner expects another `special` occasion when he plays Carlos Alcaraz for the men`s US Open title after the Italian reached his fifth successive Grand Slam final on Friday.

Sinner beat Felix Auger-Aliassime 6-1, 3-6, 6-3, 6-4 and is chasing a fifth career major after joining Rod Laver, Roger Federer and Novak Djokovic as the only men to reach all four Grand Slam finals in a season. "I think five straight Grand Slam finals, it`s something great. The consistency and putting myself there in the later stages of the biggest tournaments we have, it`s amazing," said Sinner. 

"I would have never thought that I would make this when I turned pro, and now I find myself here." His world number one ranking will be at stake on Sunday when he faces Alcaraz for the third consecutive Grand Slam final. Sinner, 24, captured the Australian Open and Wimbledon titles this season but lost to the 22-year-old Alcaraz in an epic five-set battle at the French Open.
