The glitz and glamour heralding the WTA Finals have been fun to watch, but serious business is about to begin in Singapore.
This is the biggest tournament outside the Grand Slams, a recognition of excellence and consistency through a long, hard season.
So, after over nine months of almost endless travel and intense competition, the Elite Eight must give it one final go in Singapore.
World number two, Serena Williams is a conspicuous absentee- the American brought an early conclusion to her year after failing to recover from a shoulder problem- but in her place comes Svetlana Kuznetsova, who produced a strong finish in Moscow to knock-off Johanna Konta in a late scramble for the final qualifying spot.
It completes an impressive resurgence for Kuznetsova, whose last appearance at the season-ending showpiece was in 2009- the year she won the second of her two Grand Slam titles.
With Serena missing, top seed, Angelique Kerber has already locked down the year-end number one spot, but the German leftie has got some unfinished business with the WTA Finals.
In three previous appearances, she had failed to progress beyond the group stage.
A superb year has already yielded two major titles for the German, and success in Singapore will be the perfect icing on the cake.
Kerber is joined in the Red Group by former finalist, Simona Halep, and a couple of debutants, Madison Keys and Dominika Cibulkova.
Kerber and Halep are the favourites to progress, but with the powerful Keys and the explosive Cibulkova in the vicinity, this one is far from set in stone.
The White Group is headlined by defending champion, Agnieszka Radwanska, who is making her sixth consecutive appearance at the WTA Finals.
Radwanska has once again been strong in Asia, claiming the title in Beijing, as well as reaching the semi-finals in Tokyo.
The world number three takes an eight-match winning streak to the WTA Finals, where she opens against Kuznetsova, who interestingly, was the last woman to beat her.
This is a tough match-up for Radwanska, as Kuznetsova enjoys a quite remarkable 12-4 record over the second seed.
The other players in the White Group are Garbine Muguruza, and another debutant, Karolina Pliskova.
Radwanska must feel very good about her return to Singapore, and more importantly, she is playing very well. It will be a bit if a surprise if she fails to get out of this group.
The enigmatic duo of Muguruza and Pliskova can blast anyone off the court on their day, while Kuznetsova brings form from Moscow.
This section group is loaded with intrigue.
It will be a great week in Singapore!
