Serena Williams vs. Li Na
Anyone who watched Serena vs Jankovic will be scratching their heads at the disappearance of Serena midway through the match. Actually, throughout almost the whole match, Serena was barely there. Maybe it was Summer or Tequanda, but it was definitely not a 100% healthy Serena. Still, she manages to get the job done, and survives to play Li Na. The world number 1 cannot afford to do this against the rejuvenated Li, who was clinical in her disposal of Kvitova. Serena needs to overcome her demons (which is herself) and give her all in the last match of the season. If both players play to their best, we are guaranteed a crackling final. As usual, it will be difficult to pick against Serena. But if one of her alter egos appears, Li might just become the first Asian to win the year-end championships.
Pick: Serena in 3 sets
