World number two Andy Murray eased into the third round of the Shanghai Masters with an impressive straight-set victory over America's Steve Johnson.
Murray dominated after saving a break point in the opening game, beating world number 24 Johnson 6-3 6-2.
The British number one, 29, will play 13th seed Lucas Pouille of France next.
"I played a very good match. Once I got ahead I managed to keep momentum," said Murray who secured the win in just 74 minutes.
It was Murray's third victory in three meetings with Johnson and was far easier than his 6-0 4-6 7-6 (7-2) quarter-final win at this summer's Rio Olympics.
