Britain's Andy Murray was in commanding form as he beat Lucas Pouille in straight sets to progress to the quarter-finals of the Shanghai Masters.
The world number two won 6-1 6-3 in one hour 17 minutes to set up a last-eight tie with either Gael Monfils of France or Belgium's David Goffin.
Murray played aggressively, though he will want to improve on a 46% first-serve percentage.
"I was able to dictate a lot of points. It was a good match," said Murray.
The world number two began superbly, breaking his 22-year-old opponent in the second and fourth games, and concluded an impressive first set in 39 minutes with the Frenchman making 13 unforced errors.
