US Open runner-up Daniil Medvedev continued his superb form in the second half of the season, beating Croatia’s Borna Coric 6-3 6-1 in the St Petersburg Open final on Sunday to claim his third title of the year.

Medvedev was playing in his fifth consecutive final after Washington, Montreal, Cincinnati and the US Open and the 23-year-old became the first Russian to claim the St Petersburg Open trophy since Mikhail Youzhny 15 years ago.

He broke Croatia’s Coric twice en route to taking the opening set and tightened his grip on the contest with two more breaks in the second to seal his sixth career title.

Should he maintain his form, the world No.4 will be a top contender at November’s season-ending ATP Finals in London, in which he is due to appear for the first time.
