Richard Gasquet set up a second-round clash with defending champion Jack Sock as he defeated Denis Shapovalov at the Rolex Paris Masters on Monday.
The Frenchman saw off Canada’s Shapovalov 6-4 7-6 (7-3) in an hour and 39 minutes.
Meanwhile, Serbia’s Filip Krajinovic, last year’s beaten finalist, made a first-round exit as he lost 7-5 6-2 to Russian Karen Khachanov, who will now face lucky loser Matthew Ebden.
Khachanov was due to play Kyle Edmund but the match was revised after the event tweeted to say the Briton had withdrawn from the final Masters tournament of the year.
Second seed Novak Djokovic’s opponent in round two will be Joao Sousa after the Portuguese qualifier beat Italy’s Marco Cecchinato 7-5 6-3.
And for fourth-seeded Alexander Zverev and fifth-seeded Marin Cilic it will be Frances Tiafoe and Philipp Kohlschreiber respectively. Tiafoe got past Nicolas Mahut in straight sets, while Kohlschreiber came from behind to triumph against Robin Haase.
Feliciano Lopez was another qualifier to get through, beating Alex De Minaur, and Nikoloz Basilashvili, Roberto Bautista Agut, Adrian Mannarino and Damir Dzumhur also progressed.
