Italian top seed Matteo Berrettini roared into the ATP Tour's Antalya Open quarter-finals with a straight-sets victory over Dimitar Kuzmanov.
Berrettini dropped only two points behind his first serve and broke his Bulgarian opponent five times in a dominant 6-2 6-3 win.
"The more matches I play, the better I feel," Berrettini told the ATP website.
"The conditions are pretty slow here, so you need to make sure not be too passive like at the end of the second set. But besides that, I felt good."
In the last eight Berrettini will meet Kazakhstan's Alexander Bublik, who overcome Tristan Lamasine of France 6-2 6-4.
Italian third seed Fabio Fognini lost an epic in just under three hours to Jeremy Chardy of France, 7-6 (7-4) 6-7 (1-7) 7-6 (7-5).
Chardy will next meet German Jan-Lennard Struff, who did not have to take the court in the round of 16 courtesy of a walkover from Hugo Grenier.
