Injured Maria Sharapova pulls out of US Open on eve of tournament
Third seed has been struggling with leg problem since Wimbledon

Russian third seed Maria Sharapova withdrew from the US Open on Sunday with a right leg injury, easing the path to a calendar-year grand slam for top-ranked Serena Williams.
US Open tournament director David Brewer announced Sharapova’s exit, which allowed qualifying lucky loser Daria Kasatkina of Russia into the draw.
“Unfortunately I will not be able to compete in this years US Open,” Sharapova said in a Twitter posting. “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.”
Sharapova had been the highest-seeded rival in Williams’ half of the US Open draw, a status that now belongs to seventh-seeded Serbian Ana Ivanovic, a possible semi-final foe for the 33-year-old American.
Williams is trying to complete the first grand slam calendar-year title sweep since Steffi Graf in 1988 and match Graf’s open era-record of 22 slam singles crowns.
