Maria Sharapova has withdrawn from the season-ending WTA Championships because of an injured right shoulder.
The WTA says the third-ranked Russian will miss the Oct. 22-27 tournament in Istanbul because of the injury, which has sidelined her for most of the second half of the year.
Sharapova thanked Istanbul for being a "tremendous host" and said she hopes to play in Turkey in the future.

The tournament features the top eight singles players and top four doubles teams.
