Defending champion Jannik Sinner beat world number 36 Alexei Popyrin in straight sets to secure a safe passage through to round three of the US Open.
The world number one, 24, had lost just four games in a dominant first-round victory over Vit Kopriva.
And Sinner produced another efficient display against Australian Popyrin, who upset Novak Djokovic in the third round of last year's tournament but did not threaten a repeat here.
