Tsonga wasted seven break points but finally took the advantage in the final set, with Humbert visibly disappointed to have lost a second set he dominated. It was even tougher for Marcel Granollers, who needed three tiebreak sets to prevail 7-6 (3), 6-7 (5), 7-6 (5) over Croatian Ivo Karlovic, who turns 40 this month.
Granollers of Spain next faces third-seeded Denis Shapovalov of Canada. Jeremy Chardy routed lucky loser Adrian Menendez-Maceiras of Spain 6-1, 6-1 in only 47 minutes. Chardy will meet fellow Frenchman Antoine Hoang or Belgian Steve Darcis in the second round.
