Carlos Alcaraz sealed an incredible win in the battle of the young guns against Italian Jannik Sinner to progress to his first Grand Slam semi-final in what was the US Open 's latest ever match.
The Spanish teenager finally clinched victory at 2:50am, winning 3-6 7-6(7) 7-6(0) 5-7 6-3 after five hours and 15 minutes to set up an exciting contest with American Frances Tiafoe on Friday. The 19-year-old had rescued his US Open campaign after surviving a match point scare in the fourth set.
This was the second time Alcaraz had played beyond 2am in succession after his fourth-round win over Croatian Marin Cilic finished at a late 2:23am.
