Dominic Thiem celebrates

Top seed Dominic Thiem overcame a poor start to beat Jan-Lennard Struff in the second round of the St Petersburg Open.

The Austrian lost his opening service game of the match, but hit back a couple games later to level things and then took the tie-breaker before easing to a 7-6 (7-4), 6-4 victory.

Next up for the French Open finalist is Daniil Medvedev after the Russian secured a 6-3, 6-4 victory over Mikhail Kukushkin.

Also in the top half of the draw, Mikhail Youzhny’s tennis career came to an end as he went down 7-6 (8-6), 3-6, 6-3 against fifth seed Roberto Bautista.

The 36-year-old Youzhny finishes his professional career with 10 ATP Tour singles titles and 499 victories.

“I can say I had a great career. I never thought I could play until 2018 and I can play at a high level,” he told

“I was one of the youngest guys from my age who went into the Top 100 and from all the times, I was at a high level. All the time I can say I was a professional, that’s why I maybe stayed later in the tennis career.”

Bautista will face third seed Marco Cecchinato for a place in the semi-finals after the Italian defeated Lukas Lacko 7-5, 7-6 (8-6).

Defending champion Damir Dzumhur sealed a quarter-final date with Stan Wawrinka with a 6-4, 6-4 win over Guido Pella while the eighth seed Denis Shapovalov beat Matteo Berrettini 7-6 (8-6), 4-6, 6-0.
