Fognini also beat Bautista Agut in July at Gstaad, where he won his fourth career title, all on clay. St. Petersburg, where he was a finalist in 2012, is on an indoor hard-court. The unseeded Dzumhur defeated eighth-seeded Jan-Lennard Struff of Germany 6-3, 7-5. In a match of vulnerable servers, Struff was the least effective in winning less than 30 percent of his second serves and losing his serves five times.
"I was making him play more, because he likes fast points," Dzumhur said. "I won because I didn't give him easy balls that he likes." Dzumhur, of Bosnia and Herzegovina, is at a career-high ranking of 55 after reaching his first career final last month in Winston-Salem.
He has a 0-2 win record against Fognini.
