A day after clocking up his 1,000th win on the ATP tour, Rafael Nadal made it 1,001 with a straight sets victory over Jordan Thompson.
The top seed eased through the first set 6-1 in 31 minutes. But the 26-year-old Australian showed a bit more grit in the second set. The world number 61 even carved out a set point when leading 6-5 but Nadal saved that and eventually held his serve.
The 20-time Grand Slam champion upped his game in the subsequent tie-break to secure it seven points to three and set up a quarter-final clash with fellow Spaniard Pablo Carreno Busta who accounted for the Slovakian qualifier Norbert Gombos 7-5, 6-2.
Diego Schwartzman moved into the last eight with a 6-1, 6-1 breeze past Alejandro Davidovich Fokina.
The sixth seed needed only an hour to dismantle the 21-year-old Spaniard but will face tougher opposition on Friday in the shape of the third seed Daniil Medvedev.
"It is is going to be a different match against Daniil and it will be tough because I want to be in London," said Schwartzman. "Everything is in my hands."
Medvedev battled back from a set down to beat Alex De Minaur and reach the last eight in Paris for the first time.
"When you win such matches, especially in the way I did it, playing really good, sometimes it gives you extra confidence," said the world number five. "Hopefully that's the case."
