The stage is set for the US Open semi-finals, with four of the biggest stars on the ATP Tour ready to battle for a place in the final at the season's final major.
First on Arthur Ashe Stadium, Novak Djokovic will take on Carlos Alcaraz, completing their set of meetings at all four majors. Djokovic leads their Lexus ATP Head2Head series 5-3 and has won their past two clashes.
In the second semi-final, No. 1 in the PIF ATP Rankings Jannik Sinner will continue his pursuit of a third Slam title this season when he plays Felix Auger-Aliassime. The Canadian owns a 2-1 advantage in their series, but Sinner beat him 6-0, 6-2 last month in Cincinnati.
World No. 1 is up for grabs as well. If Alcaraz matches or outperforms Sinner at Flushing Meadows, the Spaniard will return to World No. 1. Vote for your picks in the US Open semi-finals below.
