Novak Djokovic continued his Paris Masters title defence by reaching the quarter-finals.
Djokovic, seeking a record-extending seventh Bercy title this week, thrashed Russian Karen Khachanov 6-4, 6-1.
The 21-time Grand Slam champion, already the winner of a record 38 Masters crowns, will play Lorenzo Musetti for a semi-final berth.
Djokovic stretched his winning run in individual tournaments to 18 matches, dating back to his French Open quarter-final loss to Rafael Nadal in May.
The Wimbledon champion has now won 10 of his 11 meetings with Khachanov - the only defeat coming in the 2018 Paris Masters final.
He edged a tight opening set but powered to victory in the second, reeling off five straight games.
