Spain’s Carlos Alcaraz became the youngest US Open quarter-finalist in the Open Era after beating German qualifier Peter Gojowczyk in five sets at Flushing Meadows on Sunday night.

The 18-year-old Alcaraz, who upset Greek third seed Stefanos Tsitsipas in the third round, reached his first Grand Slam quarter-final with a 5-7, 6-1, 5-7, 6-2, 6-0 triumph.

Alcaraz, the world No 55, is the youngest US Open men’s quarter-finalist since Brazilian Thomaz Koch in 1963 – five years before tennis turned professional.

The Spaniard will next face Canadian 12th seed Felix Auger-Aliassime, who beat American Frances Tiafoe 4-6, 6-2, 7-6 (8/6), 6-4.

“I’m super excited to be in my first second week in the Grand Slam, so it’s amazing for me. It’s a dream come true,” Alcaraz said after he made history. “It’s really tough to play these kind of matches, to play five sets… I hope to play more second weeks, to play more quarter-finals of Grand Slams. I didn’t expect to play quarter-finals here. So I think it’s a really good performance from me in these matches.”
