Russian ace Maria Sharapova has pulled out from the ongoing St. Petersburg Open due to an injury in the right shoulder.
The 31-year old was due to play her second-round match against number 3 seed Daria Kasatkina but it was the injury that forced her to withdraw from the tournament.
Consequently, Kasatkina went on to advance to the quarterfinals of the event.
The former world no one stated that despite preparing herself for the match, she couldn't make it for the match owing to the injury.
“I tried to do everything possible to be able to be ready to compete this week, but my right shoulder continues to be an issue for me," said Sharapova, according to WTA.
"I will meet with my team of doctors over the next few days to evaluate the situation, and I look forward to returning to completion as soon as possible.
"It was so special to play in front of my home crowd this week and I wish I could have continued competing in this fantastic tournament.”
Sharapova earned her first WTA win in her native Russia for 13 years after beating Daria Gavrilova 6-0, 6-4 in the first round of the St. Petersburg Ladies Trophy on Monday.
Sharapova has rarely played the Russian tour events during her career, and when she has she's never got past the quarterfinals.
