Stan Wawrinka will face Adrian Mannarino (ATP 56) in the first round of the Swiss Indoors Basel next week.
The opening opponent for Dominic Stricker, the second Swiss player to be directly in the main draw, is Dutchman Tallon Griekspoor (ATP 37). This was the result of the draw on Saturday afternoon.
Wawrinka has never won against Mannarino. He lost the last of their three previous duels in five sets in the first round of the Australian Open at the beginning of January. Last year's Swiss Indoors quarter-finalist Stricker and Griekspoor, who lost to Grigor Dimitrov in the semi-finals in Stockholm on Saturday, have never played each other.
The top-seeded Russian Andrei Rublev, whom Wawrinka defeated in Stockholm on Friday, starts the tournament against the Portuguese Nuno Borges (ATP 32). The first opponent for the Norwegian number 2 seed Casper Ruud is Roberto Bautista Agut (ATP 60). The Canadian defending champion Félix Auger-Aliassime opens against the Argentinian Sebastian Baez (ATP 27) and could face Ruud in the quarter-finals.
The Swiss contingent will be joined in the qualifiers on Sunday. Henry Bernet (17, ATP 940) pulled off a big surprise in the first round against Fabio Fognini (ATP 76) (6:3, 7:6) and will play his compatriot Jérôme Kym on Sunday for a place in the main draw. The 21-year-old Kym from Fricktal (ATP 141) also prevailed against a higher-ranked opponent - with a 6:1, 7:6 win over Frenchman Arthur Rinderknech (ATP 62).
