The Hungarian hit four aces but was hamstrung by six double faults. Fognini's greater consistency with his first serves helped see him over the line and close the game out in one hour 40 minutes.

The late men's match saw Nikoloz Basilashvili fire six aces on the way breezing past Malek Jaziri 6-2, 6-2 in just over one hour.

Basilashvili faces No. 5 seed Kyle Edmond in the semifinals, after the Briton defeated Serbian qualifier Dusan Lajovic 6-3, 7-6.

Lajovic had shocked No. 3 seed Grigor Dimitrov in the previous round, but made a slow start as Edmond raced into a 3-0 lead that he was to keep for the remainder of the first set.

Undaunted, the Serbian came out swinging in the second set, serving up five more aces. However, Edmond stood firm and with neither player breaking serve a tiebreak was needed to settle proceedings, which Edmond ultimately edged 7-6.
