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 1, right here!
(Singles play begins at 7:30pm Singapore time - watch live here)
(1) Serena Williams (USA #1) vs (7) Ana Ivanovic (SRB #8)
Head-To-Head: Williams leads Ivanovic, 7-1
1) Serena is on the second-longest winning streak in WTA Finals history.
Serena has won her last 15 matches at the WTA Finals, going 5-0 at each of her title runs in 2009, 2012 and 2013. Only Martina Navratilova has won more in a row here - 21 between '83 and '86.
2) Nobody has won more matches in 2014 than Ivanovic.
Ivanovic has won a whopping 56 WTA main draw matches this year, which isn't just the most of anyone, but no one else has even gotten to 50. Carla Suárez Navarro is second on the list with 49.
3) Serena may be 7-1 against Ivanovic, but the gap has definitely tightened this year.
Before 2014, Serena was 4-0 against Ivanovic, never losing a set - never being pushed beyond a 6-4 set, either. Ivanovic scored her first win over Serena at the Australian Open this year, and has taken a set in two of their three meetings since then (including this summertime thriller in Stanford).
(4) Simona Halep (ROU #3) vs (5) Eugenie Bouchard (CAN #7)
Head-To-Head: Series tied, 1-1
4) This is a match-up between the only two WTA Finals debutantes in this year's field.
Not only are these the only two players making their first appearances at the WTA Finals, they're also the two leading WTA Rising Stars - the first two players born in 1991 or later to break the Top 10.
5) Their rivalry is just blossoming, and it's already tight.
The two players have split two career meetings, both this year, with Halep rallying from a break down in the third set to win in Indian Wells (highlights here) but Bouchard exacting revenge at Wimbledon.
6) Halep and Bouchard are just the third players from their countries to play this event.
Halep is the third Romanian ever to play the WTA Finals (Virginia Ruzici played it in 1983 and 1984 while Irina Spirlea played it in 1996, 1997 and 1998) and Bouchard is the third Canadian ever to play here (Carling Bassett-Seguso played in 1984 and 1985 and Helen Kelesi played in 1988 and 1989).
And there's more...
7) WTA Live All Access Hour presented by Xerox is on at 9am Singapore time.
Catch up with the elite eight about everything from the glamorous draw ceremony to their preparations for the WTA Finals, their thoughts on the round robin groups and more.
8) The stars of the future are first up on Centre Court.
The WTA Future Stars finals are first up on the Centre Court schedule, with Japan's Yuki Ando and Thailand's Thasaporn Naklo meeting in the Under 14 final and Chinese Taipei's Huang Hsiang-Wen and India's Karman Thandi meeting in the Under 16 final.
9) Four Grand Slam champions will be on the court at the same time.
At 5:30pm Singapore time, Martina Navratilova, Tracy Austin, Iva Majoli and Marion Bartoli will play the first match of the WTA Legends Classic, a doubles event where they will rotate partners during the week. First up: Navratilova and Bartoli against Austin and Majoli.
10) There's going to be a very, very special guest at the Opening Ceremony.
The elite eight will be given a dazzling welcome at the Opening Ceremony, which begins at 7pm Singapore time. From music to light shows and a special tribute to two-time Grand Slam champion and former World No.2 Li Na, it'll no doubt be a night to remember. Find out more about it here.
