Metz - Joao Sousa has saved all four break points to beat Ivan Dodig 6-2, 6-2 in the first round of the Moselle Open on Wednesday.
The sixth-seeded Sousa will next play Igor Sijsling at the indoor tournament.
Finnish veteran Jarkko Nieminen set up a meeting with former Wimbledon semi-finalist Jerzy Janowicz after beating Sergiy Stakhovsky 6-1, 6-4.
After playing a crucial part in France's 4-1 win over Czech Republic in the Davis Cup semi-finals over the weekend, top-seeded Jo-Wilfried Tsonga was to play Gilles Muller later Wednesday.
The 11th-ranked Tsonga is looking for a strong finish to his season as he still stands a chance to qualify for the ATP finals in London from 9-16 November.
Also, David Goffin advanced with a 6-2, 6-2 victory over French qualifier Florent Serra.
