Serena Ends Season Early To Focus On Health

World number one Serena Williams has opted against defending the WTA Finals title and decided to end her season early following a roller coaster campaign littered with pains and prizes, the American said on Thursday. The 34-year-old's last match was her shock loss to Italy's Roberta Vinci in the semi-finals of the U.S. Open last month, which ended her bid to become the first women in 27 years to win all four grand slam titles in the same season.
