Del Potro then competed at the newly formed Lyon Open, where he defeated lucky loser Quentin Halys, but lost in the next round against Portuguese qualifier Gastão Elias in straight sets. Doubt was cast over his participation at the French Open because of a back injury that had hampered him at Lyon, but he eventually decided to partake in the event. Del Potro entered as the 29th seed, the first time since the 2014 Australian Open that he was seeded at a Grand Slam tournament. In the first round, Del Potro defeated Guido Pella in straight sets, and in the second round against Nicolas Almagro, it was one set apiece before Almagro retired. Del Potro eventually fell in straight sets to top seed Andy Murray in the third round.
