Serena Williams defeats WTA champion Li Na for her 78thvictory and 11th title to finish the 2013 seasons. The girl is an amazing tennis player and deserves a break after this season. The 32 year old said that she is exhausted but said she had to keep going, she has a heart of a champion. She won a little over $12M in prize money not too bad for a tennis player. That is some fat cash but she worked hard for it.
