WTA FINALS: Red (Halep, Sharapova, Radwanska, Pennetta) White (Muguruza, Kvitova, Kerber, Safarova)

The final tournament of 2015 is happening on the WTA Tour this week, the "BNP Paribas WTA Finals Singapore Presented by SC Gobal." In one half of the draw lies the two top contenders Maria Sharapova, Simona Halep along with Aggie Radwanska and Flavia Pennetta. In the other half of the draw is Garbine Muguruza and three lefties: Angelique Kerber, Petra Kvitova and Lucie Safarova.

Despite the absence of Serena Williams there should be some compelling matches, but as this infographic demonstrates, the tournament is Sharapova's to lose, or a moment for Halep to step up and prove why she really is the #2 player in the world behind Serena. Sharapova has a combined 19-5 against the members of her group. (Bizarrely, the only player she has a negative record against is Pennetta! But's it only 2-3.)

Matchups I am looking forward to are Kvitova-Safarova, Sharapova-Halep and Kerber-Kvitova.
