St. Petersburg Open
Unseeded Marin Cilic of Croatia upset fifth-seeded American Taylor Fritz 7–6 (3), 4–6, 6–4 to win the title in St Petersburg, Russia.
Cilic, who lost to Aslan Karatsev in last Sunday’s final in Moscow, finished with 12 aces, won 78 percent of points on his first serve and converted five of seven break opportunities in the two-hour, 23 minute match.
It’s the second title of the season for Cilic, who also claimed the Stuttgart crown in June. He previously won this event in 2011.
