World number three Daniil Medvedev cruised into the second round of the China Open with a 6-2, 6-1 victory over Tommy Paul on Friday.
The Russian broke serve decisively in the fourth game and secured the opening set when Paul lofted a forehand long.
Medvedev then peppered the American with a barrage of powerful serves and forehands to close out the match with ease.
He will play Alex De Minaur in the second round after the Australian edged out Britain's Andy Murray in a third-set tie-break on Thursday.
"During the match, I played better and better," Medvedev said at a post-match press conference.
"I managed to serve better, to find better angles, some good returns, some good depth on my shots," the US Open runner-up said.
"It's never easy after a Grand Slam final to come back and play a big tournament, so (I'm) happy with it."
