Serena wins the WTA Championships over her sister Venus, continuing the family rivalry that has been rooted since 1998. This was their 23 match against each other, and the win added to Serena’s lead in the family scoreboard, 13-10. Serena was the obvious winner going undefeated in all five matches including the finals against her sister who had a less direct shot to the finals. Her victory won her 1.55 million dollars. To say it was an obvious win does not mean it was easy or pain free. Both sisters nursed injuries during and in between matches, and several of the athletes were forced out of the competition due to injury.
