World number one Carlos Alcaraz reached the quarter-finals at the Paris Masters with a straight-set win over Bulgarian Grigor Dimitrov.
The Spaniard will face Russian seventh seed Andrey Rublev or Denmark's Holger Rune next.
Later, Serbia's former world number one Novak Djokovic meets Russian Karen Khachanov in the third round.
Djokovic has won the title in his past two appearances, in 2019 and 2021, winning 15 of his past 16 matches in Paris - with his only loss coming against world number 19 Khachanov in the 2018 final.
Contesting his second event since winning the US Open title and becoming the top-ranked men's player in September, Alcaraz backed up his opening straight-set win over Japan's Yoshihito Nishioka with another clinical display.
