Three-time Grand Slam champion Stan Wawrinka, former world No. 4 Tomas Berdych and rising Serbian star Laslo Djere have all withdrawn from the St. Petersburg Open. Per the Russia media, Wawrinka, 34, won't be making his third main draw appearance in St.
Petersburg because of a leg injury. The Swiss has had two deep runs in St. Petersburg but he has yet to make it all the way at the Russian event. The 34-year-old ended runner-up in his St. Petersburg debut in 2016, while he made the semifinal in his second appearance at the tournament last year.
Berdych, 33, also won't be making his third appearance in St. Petersburg this year as he has pulled out of the event due to non-medical reason. Berdych, now ranked at No. 103 in the world, lost in the St. Petersburg round-of-16 in 2015 before he made the semifinal a year later.
Djere, who won his maiden ATP title this year in Rio de Janeiro and reached a career-high ranking of No. 27 in the world, will have to wait for at least one more year to make his debut in St. Petersburg.
