Maria Sharapova has confirmed that she will not compete at the 2015 US Open at Flushing Meadows after failing to recover sufficiently from a leg injury. The world number three has not played since losing 6-2, 6-4to eventual champion Serena Williams in the semi-finals at Wimbledon last month. She was previously forced to withdraw from Rogers Cup duty in Montreal and also missed the recent Cincinnati Masters tournament.

In a statement released via her official Facebook page, Sharapova wrote: "Unfortunately I will not be able to compete in this years US Open. I have done everything possible to be ready but it was just not enough time. To all my amazing fans, I will be back in the Asian swing in a few weeks and look forward to finishing the year healthy and strong."

The five-time major winner will be replaced in the women's draw by fellow Russian Daria Kasatkina, who will face Daria Gavrilova in round one on 1 September. Sharapova won her solitary US Open crown in 2006, when she beat Justine Henin in straight sets. The 28-year-old also pulled out of the tournament two years ago after suffering recurring pain in her serving shoulder following a second-place finish at Roland Garros.
