1) First time's a charm
Halep will be appearing in the BNP Paribas WTA Finals Singapore presented by SC Global for the first time - she is the 147th player to qualify for the event in its 44-year history.
2) Experience counts
In the past 30 years, only three players have won the tournament as debutantes: Serena Williams (2001), Maria Sharapova (2004) and Petra Kvitova (2011).
3) Hai Romania!
The last Romanian to appear at the WTA Finals was Irina Spirlea, in 1998.
4) Insider tips
Before Spirlea, Halep's manager and mentor, Virginia Ruzici, qualified in both 1983 and 1984.
Halep picked up sizeable points hauls on hard, clay and grass in 2014, winning titles on the first two surfaces and reaching the Wimbledon semifinals.
6) And under a roof, too
Last year, Halep showed that she is just as comfortable under the roof as she is outside, picking up titles in Moscow and Sofia.
In 2014, though, she has played just two matches indoors, losing both, to Kristina Mladenovic in Paris and Svetlana Kuznetsova in Stuttgart.
8) Title drought
Since her remarkable early summer feats, Halep has seen a slight dip in her fortunes, putting together a 7-4 win-loss record in her past five tournaments.
9) Fitness Concerns
In her final event before jetting off to Singapore, Halep reached the China Open quarterfinals only to then withdraw with a hip injury.
10) Final ranking
Although Halep is guaranteed to finish the year inside the Top 10 for the first time in her career, she still has plenty to play for. A good showing could result in her reclaiming the No.2 ranking, while an early exit puts her current No.3 spot under threat from both Kvitova and Eugenie Bouchard.
