New York, NY, USA, 13 September 2015 | AAP/

Australian young gun Alex De Minaur has suffered an inglorious exit from the US Open boys’ singles event.

Hoping to emulate fellow 16-year-old countryman Omar Jasika’s surprise run to the title last year, De Minaur lost 6-0 6-0 in the semifinals on Saturday to American fifth seed Tommy Paul.

Two years older than De Minaur, Paul qualified for the men’s event at Flushing Meadows and proved much too classy for the Australian.

De Minaur had qualified for the main draw and built a six-match winning streak en route to the last four.

Along the way, he upset more fancied Americans William Blumberg (the No.9 seed) and Michael Mmoh, seeded second.

De Minaur will next head to Glasgow to support and train with the Australian Davis Cup team, before travelling to Madrid where he will represent Australia at the Junior Davis Cup finals.
