In the first final of the WTA Championships which featured two 30-something-year-olds, world No.1 Serena Williams defeated Li Na for her 11th title this year, becoming the oldest ever champion at the prestigious tournament.
The beginning of the match was in Li's hands, as the Chinese fourth seed broke twice, without facing a break point herself, and took the set 6-2, before earning more break points in the opening game of the second set. However, the well-known Williams' force awoke then and the American prevented the break, ran off to a 3-0 lead and kept the momentum all the way to a 2-6 6-3 6-0 victory.
Williams' 2013 season was so successful that her prize money this year – $12,385,572 – is the third highest in history, counting both men and women. Regarding the earnings, Williams' season was more successful than any season of Roger Federer and Rafael Nadal, and only Novak Djokovic's 2011 and 2012 were more lucrative. (photo: © Neal Trousdale)
