The 31-year-old improves to 4-2 in his FedEx ATP Head2Head record against the German, who was bidding to record his 16th victory in 30 tour-level matches this season.
Banque Eric Sturdza Geneva Open champion Marton Fucsovics also advanced in straight sets, beating American qualifier Denis Kudla 6-3, 6-4. Fucsovics, who broke into the Top 50 of the ATP Rankings for the first time last month, dropped just two points behind his first serve throughout the 68-minute contest and saved all five break points he faced.
