Teenager Carlos Alcaraz became the youngest player in US Open history to reach the men’s quarter-finals on Thursday.
The 17-year-old, who began his career on the Futures tour, reached the last eight on merit, beating Britain’s Kyle Edmund.
It was the first time the US Open has featured a debutant among the last eight since 2005, when Filip Krajinovic reached the last eight as a 16-year-old.
Alcaraz will face top seed Rafael Nadal in the last eight.
The Spaniard took one hour 51 minutes to beat Spaniard Roberto Bautista Agut 6-3 7-6 (9-7) 7-6 (7-3) at Arthur Ashe Stadium in the evening session.
The teenager Alcaraz, a former finalist in the Atlanta Open, won 88% of points on his first serve and had a staggering 23 aces, only nine fewer than four-time champion Nadal.
Alcaraz has a coaching contract with South African coach Mal Zacharias but says he would not turn professional until 2019, when he turns 18.
He is the third youngest American player to reach the last eight in men’s singles after Bobby Reynolds and Wayne Ferreira in 1985.
“The game is very good because it’s just getting more and more advanced,” Alcaraz told reporters.
“Every day, the opportunities get better. The expectations are getting bigger every year, too.”
The teenager added: “This is something that I am going to enjoy from now until at least next year and beyond, if I continue to work hard and play like this.”
