Second seed Rafael Nadal showed his composure to overcome Adrian Mannarino 6-1 7-6 (8-6) in the China Open.
The Spaniard was in total control during the first set and he broke Mannarino three times in Beijing.
He dropped just two of the opening 11 games but his French opponent then showed some determination in the final set.
Mannarino came back from 1-3 down in the second set to force a tie-break but Nadal proved his class in the end.
Speaking after the match, he told reporters: "I think I played a fantastic first set. Great level of tennis, serving very good, hitting so good. During the second set, I slowed the rhythm a little bit and he played very well.
"I think I played with the right amount of determination in the tie-break. It's very important for my confidence to pass through these tough moments."
He will now take on Grigor Dimitrov in the final eight, after he beat sixth-seed Lucas Pouille 6-7 7-6 6-4.
