Rafael Nadal began his US Open campaign with a straight-sets win over John Millman.
Last year Millman made a noise after injuring Roger Federer in the fourth round of the tournament.
But Nadal did not allow Federer to experience the same fate, and he controlled the fight from the outset.
After two hours Nadal recorded a 6-3 6-2 6-2 win.
The 33-year-old Spaniard will face Australian challenger Thanasi Kokkinakis.
