Elsewhere in the men's draw, fifth seed Alex Zverev needed five sets to get past Dusan Lajovic from Serbia.
Zverev led by two sets before Lajovic staged a comeback. But the finalist at the Monte Carlo Masters could not sustain the challenge and the 22-year-old German steamed through the decider 6-2.

Zverev will next play Fabio Fognini, Lajovic's conqueror in Monte Carlo. The ninth seed required four sets to see off Roberto Bautista Agut from Spain.
