The US Open is approaching its latter stages, and the men’s singles semifinals are now set, with two enticing clashes awaiting.
World number one Jannik Sinner will meet Felix Auger-Aliassime for the fourth time in his career, just weeks after dominating him at the Cincinnati Open.
On the other half of the draw, second seed Carlos Alcaraz is set to face Novak Djokovic in what will mark the ninth chapter in their iconic rivalry.
It is a familiar-looking lineup in the final four at Flushing Meadows, and one that has just made ATP history.

Sinner and Djokovic have made the semifinals of all four Grand Slams this year, and are now the fourth pair in the Open Era to do so.
They follow Rod Laver and Tony Roche in 1969, Rafael Nadal and Roger Federer in 2008, along with Andy Murray and the Serb himself in 2011.

Djokovic has only gone as far as the semifinals in Melbourne, Paris and London, while Sinner has gone on to win the Australian Open, Wimbledon, and finish as runner-up in Roland Garros.
Alcaraz, on the other hand, won the French Open and reached the final at the All England Club, but only made it to the quarterfinals down under.
Each of Novak Djokovic’s defeats in Grand Slam semifinals this year
On three separate occasions in 2025, Djokovic has been two victories removed from major title number 25.
At the Australian Open, he knocked out Alcaraz in the last eight but had to retire during his semifinal with Alexander Zverev due to injury.

Djokovic dropped just one set en route to the final four at Roland Garros, but was ultimately denied a final appearance by Sinner.
He then lost to the Italian again at Wimbledon, suffering a second consecutive straight-sets defeat to him on the grass courts of SW19.
