The 19-year-old Spaniard won the duel between these young prodigies against Sinner (21) 6-3, 6-7 (7/9), 6-7 (0/7), 7-5 and 6-3 after a bloody battle of five hours and 14 minutes that ended at 02:50 in the morning in New York (01:50 CDMX).
Alcaraz will face the American Frances Tiafoe (26th ATP) in a rough semifinal this Friday, September 9, a surprise that took his compatriot and veteran tennis star, Rafael Nadal, off the grid in the round of 16.
For the man from Murcia, he already has a sure place on the podium of the world ranking and could still take the first position, for which it would be enough to reach the grand final of the US Open. For this episodes are missing, but Alcaraz is already on track.
