London: World number three Maria Sharapova will compete in her eighth WTA Finals next month in Singapore after officially qualifying this week, the women`s tennis governing body said on Thursday.
The 28-year-old Russian, who missed the U.S. Open because of injury, won the event on her debut in 2004 and has since reached the final twice in 2007 and 2012.
Grand-slam chasing Serena Williams, winner of the last three WTA end-of-year tournaments, and Romania`s Simona Halep have also booked their tickets for the Oct 23-Nov 1 event.
Five more places are still available.
