SINGAPORE - Every day we will bring you 10 things to look for from the BNP Paribas WTA Finals Singapore presented by SC Global - stats, nuggets... get your fix on all of that for Day 2, right here!
(Singles play begins at 7:30pm Singapore time - watch live here )
(2) Maria Sharapova (RUS #2) vs (8) Caroline Wozniacki (DEN #8)
Head-To-Head: Sharapova leads Wozniacki, 5-3
1) Sharapova could take No.1 from Serena after this tournament.
With Serena winning her first match on Monday, Sharapova needs to at least reach the final with a 2-1 round robin record - or win the title - to have a chance at No.1. But if Serena keeps winning, those minimum requirements will increase. Watch this space for all the updates on the year-end No.1 race!
2) Wozniacki has the longest active streak for year-end Top 10 finishes.
Though some may have more overall in their career, Wozniacki has the longest active streak for year-end Top 10 finishes with six (she's done it every year since 2009 and will do it again this year).
3) Sharapova is one of just two players here to have a winning H2H against the rest of the field.
Only two of the elite eight have a winning head-to-head record against the rest of the field combined: Serena, who's a ridiculous 50-4 lifetime against the other seven players, and Sharapova, who's 40-27 (but if you take her 2-16 record against Serena out of there she's a niftier 38-11 against them).
4) Sharapova leads this head-to-head, but Wozniacki might have an edge today.
Sharapova leads Wozniacki, 5-3, but on hardcourts they're an even 3-3, and in their only previous 2014 meeting it was Wozniacki who prevailed at the US Open. This will also be their first indoor meeting.
(3) Petra Kvitova (CZE #3) vs (6) Agnieszka Radwanska (POL #6)
Head-To-Head: Kvitova leads Radwanska, 5-1
5) Both players love fast courts - their best Grand Slam is Wimbledon.
Both Kvitova and Radwanska love playing on fast courts, and they don't get much faster than the grass courts of Wimbledon - Kvitova's only two Grand Slam finals came at the All-England Club (winning the title in 2011 and 2014) and Radwanska's only Grand Slam final came there too (runner-up in 2012).
6) Kvitova is one of only three players to win this tournament on her debut.
In the previous 43 editions of the WTA Finals, only three times has a tournament debutante gone all the way to the title, and they're all here - Serena (2001), Sharapova (2004) and Kvitova (2011).
7) Radwanska doesn't really like playing lefties.
Radwanska has had a very consistent year, putting together a 46-19 record - but within that is a dead even 3-3 record against lefties, and she's barely over .500 in her career against them (26-22).
8) But if there's one tournament she wants to play Kvitova at, it's this one.
Radwanska's only win in six career meetings with Kvitova came at the WTA Finals in Istanbul two years ago, in the round robin stage. Kvitova has won their last two meetings in straights, though.
9) The doubles draw ceremony will take place - and you can watch it unfold live.
You watched the singles draw ceremony live, and now you can do the same for the doubles draw. Come here at 11am Singapore time, which is 11pm ET, and watch it all go down courtesy of WTA Live.
10) The first WTA Rising Stars Invitational champion will be crowned.
Puerto Rico's Monica Puig and China's Zheng Saisai are the last two standing in the inaugural WTA Rising Stars Invitational, and they'll play for the title today. We've got live streaming of that too.
