The draw has been confirmed ahead of Swiss Open Gstaad which will take place between July 17-23.
The first glimpse of action post Wimbledon, it sees the return of European Clay and is one of the main stops before the US Open swing comes into full flow.
Roberto Bautista Agut, Miomir Kecmanovic, Lorenzo Sonego, Arthur Fils and Yannick Hanfmann are among those involved in Gstaad.
Stan Wawrinka too as a home hope will also return as the surface once again switches.
