Spanish teenager Carlos Alcaraz continued his sensational US Open debut by coming from behind to beat German Peter Gojowczyk in five sets and reach his first Grand Slam quarter-final.
Alcaraz, 18, recovered from two-sets-to-one down to win 5-7 6-1 5-7 6-2 6-0.
The victory sees Alcaraz become the youngest player in the Open era to reach the US Open men's last eight.
The world number 55 will face Canadian 12th seed Felix Auger-Aliassime or the USA's Frances Tiafoe next in New York.
