Alex de Minaur has confirmed his status as one of the hottest young stars in tennis with the most commanding first-round win of the US Open.

The 19-year-old swatted aside Japan’s Taro Daniel 6-0 6-1 6-2 to continue Australia’s flying start to the season’s final grand slam.

Matt Ebden, John Millman and Ajla Tomljanovic also notched impressive wins on Tuesday after Jason Kubler, Ashleigh Barty and Daria Gavrilova progressed to the second round on day one.

But in conceding just three games in three sets, no man was more dominant than de Minaur.

Clubbing 31 winners to 11 and saving the only break point he faced in 10 service games, de Minaur earned a shot at fellow young gun Frances Tiafoe, an upset winner over seeded Frenchman Adrian Mannarino.

In more brutally tough conditions at Flushing Meadows, Ebden advanced when Serbian Filip Krajnovic became the sixth men’s player of the day – and ninth of the tournament – to retire mid-match.

Ebden was leading 7-6 (7-1) 6-7 (5-7) 4-6 6-1 4-1 when the wilting 32nd seed called it quits after three hours and 38 sapping minutes.

The West Australian’s win set up a clash with German veteran Philipp Kohlschreiber.

Unlike Ebden, Tomljanovic spent barely an hour on court in seeing off wildcard play-off winner Lizette Cabrera 6-4 6-1 in a somewhat one-sided all-Australian affair.

Millman outclassed American teenage wildcard Jenson Brooksby 6-4 6-2 6-0 and next faces Italian 14th seed Fabio Fognini.

But 2011 women’s champion Samantha Stosur is out after succumbing 6-3 6-2 to second-seeded Australian Open titleholder Caroline Wozniacki.
