Serena Williams shot to the front of the pack along the Road To Singapore with her victory at the Australian Open. The coming weeks will see plenty of jostling for places behind her as the tour heads to Asia, Europe and South America.
The first opportunity for significant points comes at the BNP Paribas Fortis Diamond Games in Antwerp. Once a fixture on the tennis calendar, Antwerp is returning as a tour stop-off for the first time since 2008, when home favorite Justine Henin walked off as a popular champion.
This year's field is strong, with early Road To Singapore pacesetters Karolina Pliskova, Dominika Cibulkova and Barbora Zahlavova Strycova - who occupy ninth, 10th and 12th places in the standings - joining World No.7 Eugenie Bouchard at the Premier event.
And with 470 points up for grabs, victory will thrust the champion into the qualification picture for the BNP Paribas WTA Finals Singapore presented by SC Global.
Six thousand miles away in Pattaya City, a couple of other Singapore hopefuls are also in action. Peng Shuai and Elina Svitolina are the top two seeds at the PTT Thailand Open. Principal competition at the International event, which offers 280 points to the winner, is likely to come from Zarina Diyas, Kurumi Nara and Monica Puig, as well as two-time champion Vera Zvonareva, who won the latest match of her comeback on Monday.
The current leaderboard standings are as follows:
1. Serena Williams 2,000
2. Maria Sharapova 1,770
3. Madison Keys 890
4. Ekaterina Makarova 835
5. Simona Halep 710
5. Petra Kvitova 710
5. Venus Williams 710
8. Madison Brengle 518
9. Karolina Pliskova 490
10. Dominika Cibulkova 486
