In case you are capping WTA this week, you might want to pay attention to the race to Singapore:

This year is unique b/c five players: Lucie, Flavia, Timea, Karolina and Carla have a lot to play for, with Venus watching from the sidelines. Now, Safarova is coming back from an injury, CSN and Pliskova have been erratic lately, and Pennetta still has a massive hangover, but from the motivation point of view they will be playing hard. Case in point: CSN has just upset Cibulkova. Once the picture becomes clearer, the already qualified players might tank shamelessly.
Also, Russians and most other players will be trying hard in Moscow, which is a fairly big tourney in any case. Good luck.
